Big Bungee Piranha

"Look at my lovely flower! It's feeding time, and you're the main course, Yoshi. If I were you, I'd look for something else to feed it!"

- Kamek

Big Bungee Piranha is the castle boss of World 2 in Yoshi's Island DS. It is a giant, purple Bungee Piranha that hangs from the ceiling and lunges down to bite Yoshi. To beat it, Yoshi must eat Nipper Plants and make eggs and then stand on top of the Chomp Rock present in the boss fight. When Big Bungee Piranha reaches down to devour him, Yoshi must move out of the way quickly, and Big Bungee Piranha will bite on the Chomp Rock and howl in pain for a few seconds, revealing its weak spot: its tongue. Yoshi has to shoot an egg at the tongue before the boss revokes it. After having thrown three eggs at Big Bungee Piranha's tongue, the massive creature will be defeated and fall at Yoshi's feet. After two hits, Big Bungee Piranha will become progressively faster.

Big Bungee Piranha somewhat resembles and may have replaced Naval Piranha from Super Mario World 2: Yoshi's Island. The Big Bungee Piranha has several Bungee Buds.

Trivia

 * When the player enters the room to the boss battle, the floor and ceiling are already covered in large spiny Piranha vines. This means that this may be some kind of a nursery for the rest of the Piranha Plants in the area. It could also be an error, as Kamek did not increase the size of the Bungee Piranha until after the Yoshi arrived.
 * Big Bungee Piranha shares its weak spot with Bunson the Hot Dog: their tongue.
 * Big Bungee's level is the only boss level that doesn't have the fortress/castle music.
