Innertube Goomba

Goombas on swim rings appear in Super Mario 3D World. Only three appear in the whole game, appearing in the level Pipeline Lagoon. Normally, they are sleeping peacefully in the water, but if the player gets close, they wake up and try to attack the player and damage the player if they touch them.

Goombas on swim rings return in Captain Toad: Treasure Tracker, appearing in water levels such as Floaty Fun Water Park and Goomba Galleon. They behave the same as in Super Mario 3D World.

In the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury, Cat Goombas riding on swim rings appear.
