Biting Bullet Bills are a sub-species of Bullet Bills that appear in Yoshi's Island: Super Mario Advance 3. These foes are red in color (so are their Bill Blasters), they attack by chasing after Yoshi while trying to bite him, as the name implies. They can be defeated by being swallowed or spat out by Yoshi. When spat out, this foe looks like a regular Bullet Bill and flies downwards.
