Boo Balloon

Boo Balloons are a variant of Boos featured in Super Mario World 2: Yoshi's Island and its Game Boy Advance remake Yoshi's Island: Super Mario Advance 3. They have the appearance of a light blue balloon with a Boo's face. They appear in two levels: Bigger Boo's Fort and Don't Look Back!. Boo Balloons float around in midair like a regular balloon, and if a Yoshi touches one, he takes damage. If a Boo Balloon is hit with an egg, it inflates, and Yoshi can defeat a Boo Balloon by hitting it with an egg three times, causing it to pop.
