Chef Peepee! He was actually part of how I got into SML because the first video I ever watched was Chef PeePee gets Sick. It's sad he's not exactly used as much anymore, he was just a great character.

Few other faves, I also like Brooklyn Guy, Cody (To an extent), Goodman, Chris the Cucumber and Black Yoshi/Duggie (Idk why tho...)

Btw Delilah-
