There are Flightless Goonies which, as the name implies, are Goonies that cannot fly and run on the ground. There is a Dry Bones-like variety of Goonie, known as the Skeleton Goonie, which usually carries bombs. Bowling Goonies are fat Goonies that roll along the ground. Hefty Goonies are the flying versions of Bowling Goonies, and if Yoshi swallowed one of these and spat it out, it would turn into their flightless counterparts. They also appears in  and Yoshi games such as Yoshi's Story, Mario Kart: Super Circuit, Paper Mario and Mario & Luigi: Bowser's Inside Story.
