Smarty Pants

He is usually shown accompanied by a sticky blue hand, which represents the expressions and actions of his hands, since he lacks limbs.
It is manufactured by a brand called "Eggman", a reference to both Ralph Eggleston and Eggman Movers.

Smarty Pants is an electronic toy inspired by a roll of toilet paper. On its front, it has a pair of thin black eyebrows and two empty spaces that reveal a mint green LED screen, specifically where its eyes should be. At the bottom, there's another opening where the LED screen displays its name when it's turned on, along with three colored buttons separated by small lines: a yellow "1," a blue swirl icon, and a red "2."

Smarty Pants, a high-tech potty training toy, has all the glamour of a roll of toilet paper and an attitude that lives up to his name. Since his daughter Blaze has already outgrown the diaper stage, Smarty has spent years in sleep mode, forgotten in Blaze's old toy shed. But when he's unexpectedly recruited for an important mission, this know-it-all gets new batteries and a fresh chance to prove himself.
