Jon: "Welcome to Ultimate Muscle."
Arin: "Urutimatu Muscaru! Kinnikuman!"
Arin and Jon play two rounds, and Jon wins both of them.
The Grumps are quick to point out how silly the characters look. Jon nicknames the walrus man "Balls Face".
Jon and Arin talk a lot about the game itself, as opposed to talking about other games or their day-to-day lives.
Jon brings up the topic of MMA fighting, and Arin points out how if you weren't as strong as MMA fighters were, you would vomit from the force of their punches.
Jon, while initially enjoying the game, is quick to turn on it when he starts losing, saying, "this game is bad, it sucks, I hate it." Arin calls him out on this, telling Jon he just doesn't know how to play. Sure enough, as soon as Jon discovers how to counter Arin's attacks, he starts to like the game again.
Jon: "I will never fucking take you back. I will never take you back."
- In this episode, Arin assumes that Robin Mask is Kevin Mask's partner; in the Kinnikuman series, Robin is Kevin's father.
- He also asssumes that Seiuchin/Wally Tusket/Walrus shows his true power when he takes off his arm baandages; in the Kinnikuman Nisei manga, his arm bandages rip out when he turns evil and unlocks his hidden brutal power.
