You can fill this water tank up to the brim, and escape from the top. In order to do that, we need to fill this hole.

—The trapped mermaid

A Mermaid in a Water Tank! (貯水器の中の人魚!, Chosuiki no Naka no Ningyo!, lit. The Mermaid in the Reservoir!) is an event in Tomba! 2: The Evil Swine Return.


Free the mermaid from her water tank prison.


In order to activate the event, talk to the mermaid inside the room next to the man who seeks a cog in the Open the Water Gate event.

The next event will be activated at the same time. In order to progress in this event, that event must be cleared.

When that event is cleared, head to the left and step upon the mechanism that is connected to the water pump in order to fill the water tank and let the mermaid jump out of the tank. The event is cleared.
