Background fish

The background fish appear in the eel area.

Jellyfish puzzle

Solving the eel puzzle gives the player access to the UV Lantern. Using the lantern on the jellyfish in the background reveals a puzzle. Each jellyfish shows a Animal flute direction, which gives the player a warp song for bottom warp room.
