http://www.youtube.com/watch?feature=player_detailpage&v=JDPYImV_ndk#t=747s <- A weird boss from a weird game. A lot of people didn't really like Tails' Sky Patrol for reasons that I can understand, but hey, it's a game about my favorite Sonic character.
The 3rd Boss, Carrotia the Rabbit, has two attacks. She shoots out homing carrot missiles in pairs, usually in volleys of 2. She also attacks by blowing kisses at you that can be deflected, but I think they can also hit her? I haven't actually made it far enough to test, but you don't see it happen here.
