Course No. 19
Course No. 19 is the boss level of Sherbet Land in Wario Land: Super Mario Land 3. As it is set near the base of the iceberg, most of the level takes place underwater. The boss of this level is Hinyari.
At the start of the level, Wario finds a single Harisu and a ladder leading down to a pool of water. Pecans float above it, as well as more Harisu walking back and forth at the bottom, rendering them vulnerable only to Dragon Wario's fire and Jet Wario. If Wario is either of these forms, he can break open the half-broken blocks found halfway through to reveal a door leading to a small, flooded room with a giant block containing a giant coin. On the other side of the pool, a ladder leads back up to a door to the next room. This vertical room is inhabited by Pirate Gooms and is formed in an "S" shape where Wario must make his way downwards.
The area after the Pirate Gooms is a large, underwater ice cave Wario must swim through while avoiding spiked pillar obstacles in the walls that extend and retract. At the beginning, a trail of coins lead down into the depths; once at the bottom, Wario can carefully pass by a spiked pillar through a narrow gap into a tiny, enclosed area with more coins above a bed of spikes and a block containing a heart. When Wario heads right, there is a door on a platform above the water that leads to the checkpoint. Past the checkpoint, a bending passageway filled with more spiked pillars leads out of the water and to the next room, where a Bucket Head guards the door to the boss, Hinyari. Fighting Hinyari is not mandatory, as there is a door in the boss room that Wario can simply enter to end the level. If Wario defeats Hinyari, however, he receives five 3UP Hearts.
