Innertube Goomba

Goombas on swim rings appear in Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury. They first appear in the level Pipeline Lagoon, and are also seen in Sprawling Savanna Rabbit Run. Normally, they are sleeping peacefully in the water, but if the player gets close, they wake up and paddle towards the player, damaging them 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.

Goombas on swim rings make their Mario Kart series debut in the Singapore Speedway course from Mario Kart Tour.
