Idaho is a supporting character in The Amazing World of Gumball. He is a little potato from the countryside who follows beliefs and manners similar to the mannerisms of the Amish.
Idaho is an anthropomorphic potato, with a face, arms, and legs, all drawn in what appears to be black marker. He is one of the smallest characters in the show: only the virus, the viruses, the bacteria, and his sister are smaller than him, and only his parents and uncle are the same size as him. In season 2, his face gets smaller, and he becomes slightly darker.
Personality
Idaho, having been born and raised in the countryside, follows beliefs and mannerisms similar to the Amish, and speaks with a Southern twang. He also does not seem to be very bright. However, he is shown to be friendly and optimistic.
"The Vision": He is in the schoolyard in Gumball's imagination. Later, Gumball imagines that he is at a speech.
"The Potato": His second major role. He appears to be offended by Darwin's obsession with potatoes, when he is actually offended by Gumball calling him "brotato."
Idaho is named after the American state of Idaho, which produces more potatoes that any other state in the country and is known as "America's Potatoland."
Idaho is the smallest supporting character.
In "The Sock," when Darwin tells Tobias that Idaho did not invite him to his party, Idaho's accent is less of a countryside one and instead, turns into a North American accent.
In the early concept poster, Idaho had a lighter color.
On the DVD case, he is shown with six teeth, but he actually only has three.
"The Vision": He explodes upon seeing Gumball naked.
"The Potato": His hand gets shut in his locker when Gumball tells him about Darwin trying to overcome his potato craving.
"The Worst": He starts decomposing when Gumball and Darwin angrily growl at him.
"The Candidate": He is stepped on by Gumball, passes out in midair, is thrown at Gumball by Tobias and Anais, and is caught in the explosion of the school.
