Big Bungee Piranha

Big Bungee Piranha is the final boss of World 2 of Yoshi's Island DS. He's a giant Bungee Piranha, a sub-species of Piranha Plant that hang from ceilings and lunge down to bite you. To beat him, Yoshi rolled around a Chomp Rock. When Big Bungee tried to eat it, he got his teeth broken, eventually ending the large purple Piranha Plant.
