The Robinsons

The Robinsons are Gumball's neighbors who are fussy, mean, and consider themselves much higher class than Gumball and parents of Rocky Robinson. It is not known what type of creature/object they are.

Appearance
They are both grey-blue with large muppet style pink-purple noses, they are CGI. Their species is unknown, though they strangely resemble muppets and seem to have a thin fuzz, as their son Rocky is furry this could mean they are shaved. They have a white car which is usually parked next to The Wattersons. (The car Richard crashed into in The End)

Mr. Robinson
His first name is Gaylord. Mr. Robinson has a partical boring live. He appears to despise Gumball for annoying him all the time, as shown in "The Debt". He was squished by Gumball because Gumball accidentally pushed a lever. However, if Mr. Robinson wasn't so caught up in himself he wouldn't have been under the slow descending elevator, which Anais and Darwin were standing on.

Mrs. Robinson
Her first name is Margaret. She seems to be in a very grumpy mood all the time and might only be able to communicate through raspy hisses, grunts and snarls only decodeable by Mr. Robinson. She doesn't seem to love her husband much. She is taller than Mr. Robinson by a few inches (most likely because of her hair).
