Waterfall Cave ( Japanese: たきつぼのどうくつ Basin Cave) is a dungeon introduced in Pokémon Mystery Dungeon: Explorers of Time, Pokémon Mystery Dungeon: Explorers of Darkness and then later introduced in Pokémon Mystery Dungeon: Explorers of Sky. It is unlocked after completing the Drowzee mission at Mt. Bristle. You are sent there by Wigglytuff after doing sentry duty for the first time. Your objective is to reach the end to where you must retrieve the treasure and take it back to Wigglytuff's Guild, but after the completion of the dungeon you are washed away to Torkoal's Hot Spring.
