His skin is very soft, wrinkly and flexible, just like his entire body. This flexibility makes him capable of squeezing through very tight spaces. His skin creates glitter made of dead skin cells. His belly, mouth and paws are freckled. He has no eyelids, and he only has fur on his ears and tail. His fur is as soft as a cloud and always kind of sticky.

Bubblegum is primarily carnivorous, and only needs to eat approximately one adult human sized cadaver per month. When prey is scarce he is able to survive off sugar-rich foods for a short period too. Most of the time Bubblegum is not an aggressive creature and is actually quite docile, as long as he is not provoked. The only moment he's inclined to hurt someone is when he needs to feed. He spends most of the time sleeping in any tight hiding spot he can find. At night he likes to roam around in buildings; he is uncomfortable being outside for long periods of time.

His favorite hunting grounds are indoor playgrounds. If he happens to get spotted by a child, it wouldn't matter too much. Parents wouldn't believe it anyway if their kid told them there was a giant pink rainbow monster with a unicorn horn and glittering skin hiding in the playground.

The intelligence of his species is mediocre compared to human. They are a social species, capable of empathy. But they lack the ability to communicate and understand some abstract ideas. They understand some human concepts like cooking food, using vehicles to transport yourself, having playgrounds for amusement. But they do not understand the details of how these concepts came to be, or why they currently are the way they are. For him, these things have always existed and It's just how the world is. He also tends to be amused when humans create things that look similar to him. For example objects with rainbows, and glitter. He'll think: 'oh hey, look at that! That looks kinda like me :D'.
