From the Mondo show Happy Tree Friends, Nutty is the first in the series of Happy Tree Friends Patterns.

Nutty is a light green squirrel with a yellow diamond-shaped marking on his head and a large curled-up tail that moves when he is excited. Nutty has an addiction for candy or anything that is sugary. He has a big swirly lollipop, candy cane, small all-day sucker, and a candy apple stuck to his fur, which he even treats as his wardrobe

It is apparent that his googly eye is an amblyopia (or lazy eye, in layman’s term), as it is almost always looking down and drops down whenever he looks somewhere else; it also bounces around when he jitters. In some episodes, however, he seems to be able to control it, usually whenever he looks at an object intently.

As a result of his huge sugar intakes, Nutty is often hyperactive and jittery, and giggles more than he talks (sometimes he even giggles while he is dying). One drop of sugar makes him hyper to the point that he could create a tornado like a certain “Tasmanian Devil”, He sometimes foams at the mouth when deprived of candy or any other sugar-related item. He can go insane if left without candy for too long. It also shows that once he loses one addiction, he is susceptible to start a new one almost immediately, hinting that he probably has an addictive personality. He also becomes momentarily sad after finishing his candy
