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.
Apperance
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.
Mr.Robinson
Mr.Robinson has a partical boring live. His first name is Gaylord so no wonder. He appears to despise Gumball for annoying him all the time. also it appears that in "The Debt" he was killed by Gumball.
Mrs.Robinson
Her first name is Margret, 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. She doesn't seem to love her husband much. She is taller than Mr.Robinson by a few inches
