I finally decided to sit down and make a reference for Butter incase I want to commission an artist, or someone just wants to draw him. I decided to have his belly button be apart of his design, I think he just looks cuter with it. And I decided to give him a sort of tail fluff, most people have the abdomen used as a tail but I honestly think moths look cuter without it so I decided not to include it. Now I also want to include some more info about him and his world I couldn’t fit in the image.

Butter lives in a world of anthropomorphic animals. Though in our world animals come in so many sizes in his world they’re either small (around 2ft tall) or big (around 6ft tall). Butter is an exception for his species where he should be small like his dad, but he’s gotten so fat and round he is now the height of big specie animals. Though Butter still lives with his dad despite being 21 he does have a job. He works for Buzzy’s baked goods (a bakery) as the taste tester. Really though Buzzy hired him after the pie eating contest because seeing such a large moth drew in a huge crowd, and the same applied to his bakery. The taste testing is just an excuse to get Butter to eat more, not that Butter would need an reason to eat more, he’d do it regardless.
