Cheekums is Gideon Gleeful's pet hamster.
In "Little Dipper," Gideon tells Cheekums to guard the shrunken Dipper and Mabel while he's away eating ice cream. Cheekums is shown to have a low intelligence level when Dipper pokes him with a Q-tip and he is unresponsive. Though Mabel commands him to move numerous times, he is completely unresponsive, and she lovingly refers to him as a "big ol' dummy-dumb."
Cheekums is described as a "big ol' dummy-dum" by Mabel, as he doesn't react to anything. He doesn't seem to be afraid of Gideon or even listen to what he says.
Cheekums is a light brown hamster. He has a pink nose, black eyes and whiskers, gray claws, and two light yellow front teeth.
