The episode begins with Gumball and Darwin in their room, using the Shotofop software on their computer to make changes to a photo of them. They upload the finished product to Elmore Plus and check a friend request sent to Hector, which was denied. Upset by this, the duo heads to Hector's cave and call out to him. Instead, they are answered by his mother, a supposedly elderly (and ugly, according to Gumball) woman many times smaller than her son. Hector overhears the conversation and is told by his mother that it was nothing. So then she tells them to get off her property even though Gumball wants to talk to him.
In the schoolyard, Gumball tries to talk with Hector regarding the friend request. After shooting several spitballs at the giant's posterior, all of which land on Gumball and Darwin, Gumball decides that he is not worth his and he and denounces him as boring. This catches Hector's attention, who proceeds to ask Darwin if he is boring. Darwin calls him "much less interesting" than anyone else, to which Hector denies and claims that he 'does cool stuff.' Compelled, Gumball queries him on this.
Hector takes the two to his cave to show them his bedroom. Among the objects in the bedroom is his dead hamster, Barney. Hector is oblivious to this, convinced by his mother that it is merely "hibernating." In a nearby shelf, Darwin finds a comic book which is the first issue of Captain Punch, sparking Gumball's interest and potential fondness for the giant. He and Darwin read it and find its otherwise gritty and dark content to be written and drawn over, and has been in this condition since Hector's mother gave it to him. At their wits' end, Gumball and Darwin decided to go back home, only to be stopped by Hector who wishes to share jokes told between him and his mother. Hector begins by asking why the chicken crossed the road and answers that "it was for a perfectly legitimate reason." Gumball responds by saying it was not a joke, it was a sentence. At that point, a music box starts to play a melody, lulling Hector to sleep. Gumball finds his diary on the floor and reads it in hopes of learning his secrets. Written in the diary are instructions saying that he must not laugh, get over excited, shout, or sneeze. Gumball believes this to be a how-to guide to ruining one's life and further points out that it was his mother's doing. Just as she is mentioned, Hector's mother appears before them, demanding they state their business in her home. She and Gumball exchange words, the latter calling her out on her parental skills and the former warranting her actions. Soon after, Gumball and Darwin are asked to leave.
The following day, Gumball and Darwin are once again at the school playground eating lunch with Hector next to them on a building eating a turkey sandwich. Gumball wonders whether or not Hector is aware of the effects his mother's authority has on him. Darwin, however, says it is none of their business. Firmly believing that it is his business, an angered Gumball talks to Hector, telling him that him being boring is his mother's fault and not his own. He continues further by telling him to tell her to get him real comics and movies and is cut off by Darwin at a real live hamster because he does not want him to know. Hector responds saying she is doing what is best for him. Dissatisfied with the answer, Gumball persuades Hector through a series of rhetorical questions into leading a life less mundane than his current one, pounding on his toes all the while. With this newfound resolve, Hector seeks out to 'stand up to' his mother.
At the cave, Hector is already arguing with his mother regarding his boring life, which ends with him leaving the cave in a thunderous rampage that endangers all of Elmore. Hector's mother suspect Gumball and Darwin's involvement in her son's behavior. Gumball justifies this as improving his life. In response, she explains that just as giants are enormous, so are their emotions. That her parenting was to keep him calm, not make him boring; if a giant's emotions run rampant, the giant starts destroying things. Over the horizon, Hector is continuing with his rampage, going from the forest to Elmore itself, laying waste to whatever stands in his path, such as the Robinsons'house.
Whilst beholding the destruction, Gumball suggests using witch brooms to catch up to and stop the enraged giant. After initially explaining her profession as a cleaning lady, Hector's mother shows the two to their own enchanted brooms. At mid-flight, and in the midst of Gumball controlling his broom and adjusting to his fear of flying, the three discuss their proposed plan. In order to pacify Hector, one must fly directly into his ear and play the melody from his music box. Gumball then apologizes to her, which she accepts. She throws the music box to Gumball, but it misses him. She and Darwin then lead Hector somewhere safer, while Gumball is sent to get the music box. Gumball stops his broom but sends himself plummeting in the process. Retrieving the broom in the nick of time, Gumball takes off again, albeit with less control over the broom. He manages to catch the music box in his path and is saved by Darwin from Hector's stomping foot. With the music box in their possession, Gumball and Darwin set off for Hector's ear. But the broom is impeded by their combined weight, leaving Gumball with no choice but to scale the moving giant. He leaps towards Hector's butt and startles him, causing him to swat him off and into his fur. Darwin levels his broom with Gumball, looking on smugly and telling him to consider his own life choices before judging others'. Gumball retorts back, telling him to "take a good long look at the duck." Darwin is confused by this and collides with an oncoming duck. Having reached Hector's ear, Gumball attempts to wind up the music box, only to have it slip from his grasp after Hector's foot slides on a food van. Hector's mother orders Gumball to whistle the tune in his ear. He heeds this instruction, appeasing the giant into slumber on a football stadium. Before completely falling asleep, Gumball apologizes for his earlier remarks. Understanding the consequences of losing grip of his emotions, Hector decides to continue with his boring lifestyle. To which Gumball replies "he isn't boring, he's nuts." With Hector fast asleep, his mother and Darwin land to check on Gumball. From there, Hector's mom takes charge of her son.
Back at the Wattersons'house, Gumball and Darwin are on their computer. They receive a friend request from Hector but are unsure of what to do. Fully aware that Hector will go on yet another rampage regardless of whether the request is accepted or denied, Gumball takes the third option of smashing the computer with a hammer, ending the episode.
[Pushes his hand closer together to show that Hector's mom is small]
Gumball: And you're-you're a bit...
[Makes a facial expression, imitating Hector's mom]
Gumball: Actually, you're more like...
[Imitates Mrs. Jötunheim almost perfectly]
Gumball: Anyway, is Hector in?
Hector: [Off-screen] Mom, who is it?
Mrs. Jötunheim: Nothing to worry about, honey! [Grunts] In the absence of a door I can slam, I'm gonna do this.
[Moves her hand as if slamming a door]
Gumball: Can we at least talk to him?
Mrs. Jötunheim: Door.
Gumball: But we just want to be his friend on Elmore Plus!
Mrs. Jötunheim: My baby doesn't need friends like you!
Gumball: Ah, spoke through the door.
Mrs. Jötunheim: [Irritated] Get off my property!
[Gumball groans and him and Darwin walk away]
[The scene cuts to the outside of the school]
Gumball: [Off-screen] Come on, Hector, at least talk to us!
[Gumball and Darwin are shooting spitballs at Hector in the playground]
Gumball: Just accept our friend request [Spits]. It's just, if we have more friends online... [Spits] it makes us feel better about not having any in real life! [Spits]
[Spitball goop sticks on Hector's butt and then falls on Gumball and Darwin]
Gumball: Argh, forget it! You're boring anyway.
Hector: [Confused] What? Boring? Darwin, do you think I'm boring?
Darwin: I wouldn't say "boring." You're just... much, much, much, much, much, much, much, much, much less interesting than anyone else I know.
Gumball: [Shrugs] Eh.
Hector: But I do loads of cool stuff.
Gumball: Like what?
[The scene cuts to Hector's cave]
Hector : Well, this is my bedroom.
Gumball : Are you sure that your mom's not here? It's not that I find her witch face creepy or anything, it's just that I really don't want her to jump out on me.
[Gumball and Darwin stop, scream, and stare in horror at a disheveled hamster in a cage]
Gumball: WHAT'S THAT?!
Hector: That's my hamster, Barney.
Darwin: Dude, I think that Barney is... [Spins Barney's wheel; Barney turns upside down and falls on his head, completely motionless]
Hector: Hibernating. At least that's what my mom says.
Gumball: Yeah... hibernating...
Darwin: Dude! He's got comics! [Runs to the cabinet and takes out a comic book]
Gumball: [Takes the book from Darwin and gasps] You've got issue one of Captain Punch?! That's a collector's item! [Whispering] I take back everything I said. [Sing-song voice] You're so not booooriiiinnng. This comic is so extreme, my mom won't even let my dad read it! [Opens comic]
[A narrative of the comic begins, several parts of it have been clearly erased and drawn over with blue marker ink]
Captain Punch: No matter how much it rains, this city always smells "lovely!"
[A bell is heard ringing]
Captain Punch: What's this?! Looks like three "ski enthusiasts" have "withdrawn their" hard earned wages from the bank! Better get down there! "Safely!" Not so fast, "gentlemen!"
Ski enthusiast 1: "What a pleasant surprise, it's" Captain Punch!
Ski enthusiast 1, 2, 3: [Pull out "pointing fingers" substituting for guns] "Hey! Hey!"
Ski enthusiast 3: [Maniacal laughter] Hey!
Captain Punch: Take this! "Nice bunch of flowers!" "Hey! is there something on my shoe?"
Ski enthusiast 1: "Just some bubble gum!"
Ski enthusiast 2: [Holding a water hose] "Let me wash it off for you!"
Captain Punch: I'm going to take you down to "a nice restaurant for some swiss fondue!" My treat!
[Scene cut backs to Hector's room]
Gumball: Dude, who drew all over your comic?
Hector: That's how it was when my mom gave it to me, it's pretty cool, huh?
Gumball: Umm, I think we're going to go home now.
Hector: No, no, wait! Let me tell some jokes, me and my mom do it all the time.
Gumball: [Sighs lengthily] Fine.
Hector: Why did the chicken cross the road?
Hector: For a perfectly legitimate reason! He heh.
Gumball: Dude, that's not a joke, that's a sentence.
[A music box on a pillow starts playing]
Hector: [Yawns] Bed time. [Falls asleep]
[The music box stops]
Gumball: Hmm... Hector's diary. [Reads diary entry] "I must not laugh, I must not get overexcited, I must not shout, I must not sneeze"? This sounds like a How-To Guide for ruining your life!
Darwin: Who makes him write all this stuff?
Gumball: [Tosses diary aside] I think I have an idea.
[Gumball does an impression of Mrs. Jötunheim, who happens to be right behind them]
Mrs. Jötunheim: [Off-screen] I think he means me!
Gumball: [Screams] I knew she'd creep up on me!
Mrs. Jötunheim: What are you doing in my son's bedroom?!
Gumball: What are you doing taking the fun out of his life?!
Mrs. Jötunheim: I think you're being a little presumptuous telling me how to raise my son.
Gumball: Well, you know what else is presumptuous...? YOUR FACE!
Mrs. Jötunheim: You don't know what presumptuous means, do you?
Gumball: [Scoffs] Yeah...
Mrs. Jötunheim: Just get out.
[Gumball and Darwin start to leave. Outside the cave, Gumball scoffs]
Gumball: Bet you she is a witch.
Darwin: I think you've been insulting enough for today.
Let Your Heart Beat
[Gumball, Darwin and Hector are having lunch in the playground as the school bell rings]
Gumball: Do you think Hector knows what his mom is doing to him?
Darwin: I don't really think it's any of our business.
Gumball: None of our business?! She's the reason we've got no friends on Elmore Plus! Yup, that's it! I'm going to speak to him.
[Gumball angrily throws his sandwich on the ground and walks up to Hector]
Gumball: Hector! I've been thinking! It's not your fault you're boring!
[Hector is loudly chewing his sandwich]
Gumball: Uh, you've got a bit of turkey sandwich just there. [Points to his chin]
[Gumball screams as he and Darwin jump away from a giant turkey that falls to the ground]
Gumball: Look, it's your mom's fault you're boring.
Darwin: She's just strict, man.
Gumball: You go tell her to give you some real comics, some real movies and a real. Life. HAMST—
[Darwin quickly covers Gumball's mouth and slowly shakes his head at him]
Hector: But she does those things because that's what's best for me.
Gumball: Best for you?! Best for you?![Walks closer to Hector] Is it best you don't laugh?! Is it best you don't cry?! Is it best you don't sneeze?! [Slams his fist on Hector's foot] Is there a heart in that chest of yours, Hector?! 'Cause if there is, [Slams both fists on Hector's foot] let it beat, man! Let it beat!
[Darwin walks up to Gumball]
Darwin: That's his toe.
Gumball: [Whispers] I know. So, are you going to stand up to her, or not?!
Hector: [Stands up] Yes, I AAAAMM!![Slams his foot]
[As Hector walks off, the slamming of his steps create an earthquake, causing Gumball and Darwin's faces to get all jumbled up]
I'm Not Boring!
[At Hector's cave, Gumball and Darwin approach the entrance and hear Hector yelling]
Hector: [Off-screen] No, you listen! Everyone thinks I'm boring and I'm fed up with it! I'll show them I'm not![Walks out of the cave, crying]
Mrs. Jötunheim: Calm down, honey! Try your breathing technique!
Hector: [Calling off-screen] That's boring, too!
Mrs. Jötunheim: What have you done to my son?!
Gumball: Improved his life?
Mrs. Jötunheim: What's the one thing you know about giants?!
Gumball: ...That they're big?
Mrs. Jötunheim: Yes, and so are their emotions! I wasn't making his life boring, I was making his life calm! You have to keep giants calm!
Mrs. Jötunheim: Because if you don't, then that happens!
[In the distance, Hector is attacking the town and causing destruction]
Hector: IS THIS BORING, OR THIS?! DO YOU THINK THIS IS BORING?! CALL ME BORING NOW! [Swipes down the Robinson's house] IS THIS BORING?!
[Margaret is in shock about the house]
Gaylord: [Reading newspaper] Close the window, Margaret.
Donut Cop: Freeze! Police!
[Hector squashes the police car]
Donut Cop: Well, uhh, I think I'll-uh call it a day. [Runs off on foot]
[Hector approaches the senior citizens and yells]
Hector: I'M NOT BOOOORIIIINGGG!!!
[The senior citizens, except for Louie, are blown away]
Louie: What did he say?
[Back at Hector's Cave]
Darwin: Gumball, what do we do? We have to stop him!
Gumball: [Notices brooms in the cave] I got it! [Grabs a broom] We'll just fly after him using one of your witch brooms! [Attempts to "fly," but falls flat on his face]
Mrs. Jötunheim: That's a normal broomstick. I'm a cleaning lady.
Gumball: [Face down on the ground] Oh.
Mrs. Jötunheim: [Takes off her hair clip] The witchy ones are over there.
Gumball: [Quietly] I knew it.
[Gumball, Darwin, and Mrs. Jötunheim fly after Hector]
Hector: I'm not boring! I'm not boring!
Mrs. Jötunheim: How ya doing?
Darwin: Pretty good.
Gumball: What the? Hooo. Do we really have to be this high?
Mrs. Jötunheim: Yes! We need to be close to his head so he can hear the [Takes out Hector's music box] music box and fall asleep!
Hector: I'm not boring! I'm not boring! [Damages several houses and continues running]
Gumball: Mrs. Jötunheim? For the record, before we go on, I'd like to apologize.
Mrs. Jötunheim: Nah, don't sweat it kid. Now I'll try to calm him down. You take the music box. Here! [Throws the music box at Gumball, but it falls short and drops down] Ah, just go get it! We'll lead him somewhere safer!
Gumball: O-kay, how do you stop this thing? [Manages to stop the broom] A-ha! [Falls out of the sky, and starts screaming]
[Gumball starts "swimming" towards the broom, and reaches for it. He screams as he sees the ground below him. He struggles to reach the broom and manages to get on it, and slow down just inches from the street. He nervously laughs in relief, but screams as the broom picks up speed again and goes down the street. The Senior citizens have just made it back to their seats, but get blown off once more as Gumball flies past them, except Louie who just falls off his chair. Gumball loses his grip and falls off the broom, and rolls on the asphalt, eventually grinding to a halt right next to the music box. Gumball yet again laughs nervously, then screams as he sees Hector's foot coming down on him, but Darwin dashes by and saves Gumball]
Gumball: [Screaming] Oh.
Darwin: Hey Gumball.
Gumball: Darwin! Get me to that ear!
[They fly towards Hector]
Darwin: Hey Gumball, we're too heavy! You're gonna have to jump!
Gumball: Jump? What the- [Glances at Hector and is shocked] Can't you just get a little bit higher?
[Gumball points to Darwin that Hector's butt is all that they can reach]
Darwin: Just get on with it!
Gumball: [Sighs] Fine! [Jumps and grabs hold of Hector's butt]
[Hector screams in pain and hits Gumball, who flies in the air and manages to grab hold of Hector' arm]
Mrs. Jötunheim: Follow me, sweetie!
Hector: Wait for me, mom.
[Gumball climbs Hector's back with extreme difficulty. He then notices Darwin flying nearby with a smile on his face]
Gumball: What's with the smug face?
Darwin: Nothing. But I think there might be a lesson in all this. You know, next time you want to judge other people's life choices, maybe you should take a long hard look at your own!
Gumball: Well, maybe you should take a long hard look at that duck.
Darwin: Duck? [Is hit in the face by a flying duck]
Hector: [Destroys electrical lines] Get outta my way!
Mrs. Jötunheim: Hurry up, kid! I'll try and lead him to the stadium!
[Gumball makes it to Hector's ear and starts winding the music box]
Hector: Mom! Wait for me, mom!
[Hector slips on a banana truck causing Gumball to lose his hold on the music box, which falls off]
Mrs. Jötunheim: [Nearly inaudible] Whistle it!
Mrs. Jötunheim: Whistle the tune in his ear!
Gumball: Okay! [Approaches Hector's ear and starts whistling]
[Hector arrives at the stadium, yawning. As Gumball finishes the tune, Hector collapses]
Gumball: Hector, uh... I'm sorry for calling you boring.
Hector: I'm not sure all this excitement suits me, or anyone else. I think I'll just go back to being boring.
Gumball: You're not boring, dude. You're nuts.
[Hector starts snoring, and Gumball chuckles]
Mrs. Jötunheim: You okay, kid?
Gumball: Yeah! We're good.
Mrs. Jötunheim: Great! I'll take care of him from here!
How to Deal with Friend Requests
[The Watterson household, the computer in the kids' bedroom makes a ping sound]
Darwin: We got a friend request!
Gumball: Who is it? Oh, man, it's from Hector.
Darwin: What shall we do? If we say yes, he'll get excited and trash the town. If we say no, he'll get sad and trash the town.
Gumball: Don't worry, I know exactly what to do.
[Gumball takes out a hammer and smashes it into the computer screen, at which point the episode ends]
