Just Chin-Chillin | Women's Pullover
Just chill with this cute chinchilla design featuring the text “Just Chin-Chillin” with an illustration of a chinchilla eating pizza. Perfect for a chill day, lazy day, animal puns, animal gifts, chill jokes, love pizza, and chinchillas!
My exact words upon seeing this, "It's a Chinchilla! I have one of those!"
Chinchillas' butts are so round and fluffy, they look unreal. - Album on Imgur
