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 black. He is very small, and is quite possibly the smallest character in the show so far (excluding Virus, Viruses, Bacteria, and his sister, who are smaller than him, and his parents and uncle, who 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.
Idaho's name is based on the state of Idaho, which is sometimes called "The Potato State."
Idaho is the smallest supporting character, and the smallest character in the show (excluding Virus).
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 normal 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 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.
