Since he was built up by childrens (and the members of the staff) taking old parts from the backstage, the staff wanted him to play songs for the kids so they won't get tired of him.

They also gave him a voice to "voice acting" the puppet characters when he's behind the curtains of the theater.

Meow is not the only puppet of course, but he's the only one who can actually move and talk.

So yeah, I wanted to add a spicy backstory to ProtoCoso and Meow, hope you've liked it! :D
