Larry stumbles across a strange warp pipe that randomly appeared inside the castle, however this pipe contains a parallel universe, where everyone acts completely differently.
Tropes:
- Help, I'm Stuck!: Roy ends up being stuck inside the pipe as he attempts to follow the others into the parallel universe.
- No Ending: The episode ends with the Koopalings still in the 8-bit universe, and Parallel Wendy asks how they are going to get back out.
- Parallel Universe: The episode centers around the Koopalings finding a warp pipe that brings them into a universe where they meet alternate versions of themselves who act quite differently.
- "The Reason You Suck" Speech: Bowser gives his Parallel Universe counterpart one of these after the latter calls him a terrible father.Bowser: Alright, you big red prick, listen up! I've been a nice guy up until now, but if you wanna fire shots at my parenting, then I'll have no choice but to fire back! You're an overly protective control freak and you can't raise kids for squat! You won't let them do anything and they all probably hate you! And for the record, I do that recipe way better!
- Retraux: The last dimension that we see in this episode has a style very reminiscent to that of the original Super Mario Bros..
- Scream Discretion Shot: When Larry meets his parallel counterpart, we cut to a shot of the parallel castle accompanied by them both screaming.
- This Cannot Be!: Ludwig has this reaction when he finds out that his parallel self is a northerner.
