Octoombas are variants of Goombas that appear in many galaxies under the order of King Kaliente. However, unlike Goombas, they are blue with spots of yellow. They have glowing antenna and flipper like feet.
On Mario's first interstellar adventure, they would hop around, stopping to headbutt Mario if he got near. However, in his second interstellar adventure, they could spit rocks at him in a similar manner to Octorok.
