Hefty Goonies[1] are fat 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. Either hitting it with an egg or slurping one and spitting it out will turn it into a Bowling Goonie.
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. You cannot see the sprite of the normal Hefty Goonie.
A Hefty Goonie appears on Lakitu's stage in Tetris Attack.
