Flightless Goonie

Flightless Goonies are Goonies without wings. They appear in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, Yoshi Touch & Go, Yoshi's Island DS, Yoshi's New Island, Yoshi's Woolly World, Poochy & Yoshi's Woolly World and Yoshi's Crafted World.

In the Yoshi's Island games, if a Yoshi eats a Goonie and then spits it out, throws an egg at it, or spits out an enemy at it, it will become a Flightless Goonie, though, some of them already lack wings. Different from other enemies, stomping on them will not send Yoshi into the air. Later in the games, Flightless Skeleton Goonies appear. A Flightless Goonie's primary method of attack is running into Yoshi. They usually appear in packs.

Super Mario World 2: Yoshi's Island

 * Player's Guide: If you hit a Goonie with an egg, or eat one and spit it out, its wings will fall off and it will run away even faster than it flew.

Yoshi Touch & Go

 * Shogakukan guide: 羽が取れたあほ一どり. 地面に落下すると、せかせかと画面外へ駆けていく. 足が速いので、地上で倒すのは難しい. 着地前をねらってタマゴを当てたい. (A foolhardy bird with its wings removed. When they fall to the ground, they rush off the screen. It is difficult to defeat them on the ground because they are fast. Aim to hit it with an egg before it lands.)
