Get in the Tea Cup
From the Super Mario Wiki
Get in the Tea Cup is the third story of chapter two in the game Wario Land II. It is a level based on a flooded underground cavern. Wario must travel through the tunnels in order to reach the SS Tea Cup, the Black Sugar Gang's ship. The cavern houses many aquatic enemies such as sawfish and eels that drag him down if the player is careless. At the end the SS Tea Cup awaits.
Hidden Treasure: Jewel
The hidden treasure of this level, the Jewel, can be hard to find; it is located in the eel cavern, behind the water flow at the bottom of the cave. Wario cannot swim against the currents, so he has to cross it in other ways. If the player approaches the eel to the far right of the area, it drags Wario down and the player is able to reach the door. This process causes Wario to lose coins.
