Aqua Goomba

Aqua Kuribō are enemies that appear in Super Mario Land 2: 6 Golden Coins. They are Goombas wearing s. In the Turtle Zone's final stage, several Aqua Kuribō are found in the belly of the giant whale. Despite their name and appearance, they generally appear free from the water and behave largely like regular Goombas, with the only difference being that they are not flattened when jumped on.
