Peppino Spaghetti was someone who your supposed to beat and not let pass. Pizza Face told you that if he gets to you then beat him. So you just wait there and guard the floor before Pizza Face. Then suddenly you heard someone walk in. It was Peppino meaning he beat Pepperman, Noise, Vigilante and Fake Peppino.

Peppino: "Alright. Let's see whose next. Huh? Alright I assume your the last one before Pizza Face. I will not let him destroy my restaurant. So please make this easy. I'm getting tired of all these bosses."
