Smosh

Smosh is a YouTube channel originally consisting of Ian Hecox and Anthony Padilla. The main characters were transported into it in Chapter 1 Part 1, after Roger did a pina colada dance. In their first appearance, they watched Food Battle and later got stuck in Team Fortress 2, where they were murdered by SpongeBob SquarePants with the head of a dead fish, only to become zombies. They later notably appeared in Chapter 1 Part 25.
