٩.﹊ .• [042] 「Cosmo.」ˊ •.დ

Cosmo is a helpful yet cautious Toon. As confirmed by Dandy's dialogue when purchasing Cosmo, he stands out for his sweet and caring personality. He often gives sweets to other Toons to cheer them up and compliments them when he senses they need it. However, he also seems quite anxious, as shown in his dialogue whenever he completes a Machine or descends to the lower Floors. It can be assumed that Cosmo's hobby—baking—is both a source of comfort for him and a desire to help others.

He doesn't understand some jokes and can be quite susceptible to teasing, such as in his interactions with Finn GG, but he always cares about his friends and encourages them when they need it most. It should be noted that, while Cosmo can be quite gentle and anxious, he can also be quite playful.
Cosmo and Ginger are cousins.
Cosmo is Sprout's best friend.
Appearance: His hair is almost tousled. His hair is brown, and he has white frosting sprinkled on top of his head in a wavy pattern. He has six star-shaped sprinkles on his cheeks in turquoise, pink, and lime colors that resemble freckles. He wears a white hooded sweatshirt with black drawstrings and a white trim along the bottom hem, and black shorts. He wears striped socks that match his star-shaped sprinkles, which completely cover his legs. Cosmo has confirmed that the star-shaped sprinkles on his cheeks are permanent and are part of his design.
