GalZoo Island:Omake dungeon

Access
The Omake dungeon is accessable from Elina's tent, after she has been captured. The monsters in there are several times stronger that normal, and provide more exp points. Before you start to desperate (like I did...), this seems to be acessible only during your 2nd playthrough.

On each floor (except the last floor) there are three rooms whose door have Gal Monsters drawn on them. You much have the corresponding Gal Monster in your party in order to enter that room. In the middle of the room you will face a strong version of that same girl monster. After defeating her you will get the "Gal Monster Coin" item.
