The Cookie Creature

The Cookie Creature is an antagonistic little creature who lives in the walls of the Sinclair family's house.

The creature steals cookies from Baby Sinclair, much to the disbelief of his mother, who assumes the baby has actually just eaten the cookies. Baby Sinclair wages war on the creature in the "Nuts to War" episode of Dinosaurs.

Baby: My cookie's gone! Fran: That's because you ate it. Baby: No! The cookie creature took it. Fran: Oh, right, the cookie creature took it. Baby: Don't talk down to me! Fran: This is between you and the cookie creature, so you two will have to work it out. Baby: Well, thanks for nothing.
