Whirly Fly Guy

Whirly Fly Guys are a rare variety of Fly Guys found in the game Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. They flash several different colors, distinguishing them from ordinary Fly Guys. They first stand on the ground, and when the Yoshi approaches it, it slowly takes off into the sky. The Yoshi can't stomp the Whirly Fly Guy. If a Yoshi swallows one, then spits it out, the Whirly Fly Guy turns into a green Shy Guy. They are much like normal Fly Guys at first, but when a Yoshi eats a Green Watermelon, and attempts to shoot at the Whirly Fly Guy with seeds, coins start to appear from the Whirly Fly Guy. When the Yoshi shoots enough seeds at the Whirly Fly Guy, one or two Extra Lifes are awarded to the Yoshi as the Whirly Fly Guy is defeated.

They appear once again in the game Yoshi Touch & Go, but they act slightly differently than before. Here, they hide in the grass, and when Yoshi approaches, they instantly zoom into the sky. If the player defeats it before it flies away, they are awarded with four points.
