In Episode 6, Mouser appears at the Unemployment Office. Later in the episode, a smaller version of Mouser rushes past Hal and steals his sack. When Hal shouts "He took my sack!", Jasper the Kamek flies by and asks if Hal is gay.
In Episode 7, Mouser is part of Team Super Awesome Dynamite Platinum Bros. during the Villains' Olympics, along with Mega Mole and Chomp Bro. He threatens to blow up Hal and Jeff and later bombs part of Team Shy Guy to allow himself to score during the soccer event. Team Super Awesome Dynamite Platinum Bros. place first at the end of the competition and are awarded with an expenses-paid trip to Yoshi's Island, while Hal and Jeff, who place second, are awarded the cash prize. On the island, Chomp Bro. is seen trying to save Monty from being swallowed by a Yoshi, while Mouser is confronted by several of the creatures and starts to panic.
