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.

Super Mario World 2: Yoshi's Island

 * Shogakukan guide: 「太りすぎて飛べなくなったあほ一どり. タマゴを当てたり、食べて吐き出すと、羽が取れて転がってゆく. 」 (A Goonie that became too fat to fly. When hit by an egg, or when eaten, the feathers are taken off and it will roll along.)
 * Player's Guide: Too much bird feed and TV makes for one roly-poly Goonie. Even Yoshi can fly better than this guy.

Yoshi's Island: Super Mario Advance 3

 * Shogakukan guide: 「太りすぎて飛べなくなったあほ一どり. タマゴを当てたり、食べてはき出すと、つばさが取れて転がって行く. 転がっている間も、当たればイタいぞ. 」 (A Goonie that became too fat to fly. When hit by an egg, or when eaten, the wings are taken off and it will roll along. While rolling, it is also vulnerable to hits.)

Yoshi's New Island

 * Shogakukan guide: 「ボールのように丸まったあほーどり. はずむように移動するものと、地箇を転がるものの2種類がいる. はずんで移動するタイプだけ、食べて口に含むことができる. 」 (A rolling Goonie that looks like a ball. Those that bounce to move, and those that roll on the ground consist of the two varieties. For the bounce movement type, it can fit in your mouth and be eaten.)
