Hefty Goonie

Hefty Goonies are Goonies that appear in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. Due to their large weight, however, Hefty Goonies can barely fly and instead of flying, they bounce. Either hitting it with an egg or slurping one and spitting it out will turn it into a Bowling Goonie.

Despite Hefty Goonies not appearing in Yoshi's Island DS, Moltz the Very Goonie acts as the boss of World 5-4. He is the only Hefty Goonie in the game.

A Hefty Goonie appears on Lakitu's stage in Tetris Attack.

 * Official Nintendo Player's Guide: Too much bird feed and TV makes for one roly-poly Goonie. Even Yoshi can fly better than this guy.
