Cane’s Cup is… well, he’s a fountain drink cup, with the Raising Cane’s logo on him. He’s a red cup, with a plastic top, and a straw inside him. Unlike other characters, his eyes are hollowed out and white.
Cane’s Cup appears to be full of some type of cola, but it’s presumed he can change it to other things.

Cane’s Cup is calm, carefree, and comedic. The only time he’s seen worried or stressed, is when his straw disappears in episode 1 of Animatic Battle.
