Big Bungee Piranha's Lair

Big Bungee Piranha's Lair is the eighth and final level of World 2 in Yoshi's Island DS, where Big Bungee Piranha is the boss. It takes place inside of a sewer instead of a castle like all other final levels in every other world. Dizzy Dandies make their debut, as well as Wall Lakitus. This level is similar to Super Mario World 2: Yoshi's Island's Naval Piranha's Castle. Unlike the other castle levels in the game, this level plays the cave music rather than the castle music. This level's playable Yoshi is the blue Yoshi.

Layout
Yoshi starts the level in a rocky place with a Shy Guy-producing pipe nearby. He has to enter another pipe and appear in a sewer-like area with a multitude of arrow blocks. The player has to navigate through an arrow block network and continue on to the next area which houses a Stork Stop, an Egg Block, and a few enemies. After getting past another arrow block network, the Yoshi reaches an enemy-infested area which eventually leads him outside. The player has to reach the end of the area and use a Chomp Rock to be able to enter a nearby pipe. In this area, Yoshi has to repeatedly hit a Gobblin with eggs until it is defeated, allowing him passage to the next area. Here, Yoshi can find a Middle Ring and an Egg Block which are followed by a maze-like area filled with enemies. After that, the player finds a Middle Ring, a Stork Stop, and the boss door which leads to the fight with Big Bungee Piranha. Yoshi can defeat it by leading it to bite a Chomp Rock and then hitting its tongue with an egg. After this, he can continue on to World 3.
