Cosmo

Cosmo is a brown cake that resembles a Swiss roll. He has white frosting drizzled in a wavy pattern on the top of his head, which is paired with cyan, pink, and lime-colored star-shaped sprinkles as freckles. He wears a white sleeveless sweatshirt with black drawstrings and a white hem at the bottom. He has striped socks the same color as his sprinkle freckles that completely cover his legs.
Cosmo is a helpful, but cautious character. He displays anxiety in his dialogue whenever he finishes a machine or goes down to the lower floors. He seems to have a recurring theme of self-sacrifice with his character, often seeking reassurance with his baking and going out of his way to help the other characters. He can be a bit clueless in some jokes and somewhat gullible to teasing, such as in his interactions with Finn and Gigi, but he always makes sure to look out for his friends and encourage them when they need it most.
