Captain Goomba

History
After Bowser teamed up with Mario and Luigi to help save Princess Peach's voice from Cackletta, they venture on the Koopa Cruiser where Captain Goomba is seen inside a barrel, along with another Goomba, also hiding in a barrel next to him. The Koopalings, Larry, Roy, and Wendy arrive and tell the two Goombas their duty as they berate them for being stomped on by Mario. Just then, however, the Koopa Cruiser has taken serious damage by Cackletta after she appeared before Bowser, Mario and Luigi and caused the airship to crash.

Captain Goomba regains consciousness and finds himself underground. After he quickly finds his way out, he sees Bowser flying past him. Before he could go after him, he practices attacking boulder. As he went off, he ran into one of Cackletta's bean minions and broke into battle with it after Captain Goomba insulted it in their quick argument from seeing each other. After Captain Goomba defeats the bean creature, he runs into his fellow Goomba comrades who make him their leader as they planted a flag on his head, although it was actually a ruse as the other Goombas wanted to escape the job of responsibility.
