The Butterfly

"The Butterfly" is the twenty-seventh episode of Season 3 of The Amazing World of Gumball and the 103rd episode overall.

Synopsis
After a butterfly emerges from its chrysalis, Gumball releases it, and it wreaks havoc all over Elmore.

Plot
During Miss Simian's class, Darwin is inspecting something with his microscope. After he learns that he was inspecting Banana Joe's butt up close all along, he sees everything with butts on them, panicking that everything is ruined (except for Miss Simian's face, which he says looks better). Miss Simian asks them to pay attention to a chrysalis in a jar on her desk, explaining the life cycle of a caterpillar. She promptly sends Banana Joe to Mr. Small's office when Banana Joe flaps his peel "inappropriately" like a butterfly.

When Penny asks if the butterfly can be released after emerging, Miss Simian objects, and tells everyone about the butterfly effect. She demonstrates something like it by causing destructive events in the classroom that ends with a window hitting Tobias's head. Just before she asks them to witness the butterfly's emergence, the class bell rings and she drops her lesson.

Just as Miss Simian and the others leave, Gumball and Darwin see the chrysalis moving and panic. After Gumball takes a hot shower and they both breathe rapidly, the butterfly emerges. The brothers are thrilled by it, and decide to let it free.

At their break time, two construction men have some coffee. When they toast, their mugs break due to their powerful bodies. When the butterfly from earlier lands on one of their heads, the other tries to smack it off but instead punches his friend to a wall. The two men start unintentionally beating each other, all the while apologizing until one loses his arms, and the other has his head sent up to the sky towards a plane. The head says hi to a friend before falling back down.

The next scene shows Mr. Robinson driving his car. While on the road, he drives slowly and sings much to the annoyance of the workers driving to work behind him. Mr. Robinson doesn't care, saying he has all the time in the world and that he's retired. Then he starts taunting citizens (like Larry, by taking his parking space, and the Hobo, by tricking him into hitting a pole). In the latter the Hobo shouts after Mr. Robinson, wishing that he would get what he deserved. The construction man's head then hits Mr. Robinson, and knocks him out. As the Hobo steals 20 dollars from Mr. Robinson's wallet, a wheel from the latter's wrecked car knocks the Hobo unconscious. The 20 dollars flies away with the wind.

Many citizens in Elmore notice the flying bill, and compete with each other for it. The money lands near Marvin, who tries to reach it. But his fragile body prevents him from doing so, and Marvin repeatedly prevents himself from falling down with his cane. The Doughnut Sheriff shows up, and fines Marvin 20 dollars for street dancing without a license. When the officer tries to take the bill he rolls down the street and hits a pole, sending one of his shoes flying.

Nearby, the old lizard woman feeds the pigeons, then feeds on one of them. When Rocky passes by with a bagel, the shoe hits him and makes him inadvertently lean to the lady with the bagel held as if it were a wedding ring. The old lizard woman sees this and accepts Rocky, thinking he was proposing marriage. After the old woman explains her sacrifices for the "moment," Rocky says he "changed his mind" and tries to disappear. He ends up hurting himself, and the old lady calls the Elmore help desk.

At the Elmore help desk office, Karen receives the old lizard woman's call saying she was abandoned by her fiancee. As they sing/talk, Rocky also calls Karen saying that a crazy lady alligator wants to be his bride. Marvin also calls, and says that he (still being stuck with the 20 dollars) will need help standing straight. Mr. Robinson also calls, shouting that he wants to sue whoever made him wreck his car. Karen gets angry with his attitude, and the construction man's head calls too. After they make her angry with all their issues, Karen hangs up on all of them, and throws her desk out of her office.

The desk causes cars to crash into each other, and people to topple over. The people create a domino effect which ends when Hector falls on Sussie's dad. He sneezes, and this causes Charlie to be blown into a roundabout. Rosie nearby panics when the roundabout spins so rapidly that a small tornado materializes. But she calms down when the tornado disappears, and Charlie is launched into the sky. He lands in the Watterson's TV while the weather news is on, causing a tornado to form and Richard to be sucked in it.

Back at Elmore Junior High, Miss Simian returns from her break. She is shocked when she sees that the butterfly is gone. Gumball and Darwin freely admit that they were the ones who did the "decent thing," and released the butterfly. Miss Simian gets frightened, and takes cover. The butterfly comes back, and Gumball wonders how something so tiny could destroy a whole town. He gets his answer when the butterfly flies away from his view, and reveals a tornado that heads towards them.

Cultural References

 * The Butterfly effect is a real principle in chaos theory, the classic example of which theorizes that a butterfly flapping its wings can alter the path of a tornado or even cause one through a domino effect. This theory was made popular by the film named after it.
 * The construction worker losing his arms and remarking that it was "only a flesh wound" is a reference to the Black Knight from Monty Python and the Holy Grail.
