A tentacle pool is a pool of slimy water that can be built in a player-owned house's Oubliette. When challenge mode is on in the dungeon, players who fall in the dungeon will be attacked by a tentacle-like creature, and it can inflict from 0-40 life points. It cannot be attacked back. If challenge mode is not on, however, the player will just 'swim' in the pool.
