A silverfish that lives in the theatre's walls. Though, the silverfish may just seem like an ordinary silverfish, but it can play really well with note blocks, as well as (somehow) being good at fighting. When Green and the color gang was doing their play in the theatre, the silverfish was interested in trying to be part of the play, but Green didn't allow it. The silverfish decided to just intrude in Green's play, "ruining" for them but it was actually just trying to help.
