Pokémon Mystery Dungeon: Explorers of Time and Darkness

A Chimchar meets a Piplup with its head stuck in the sand. As it turns out, this Piplup was once a human, with no recollection of how it happened. Chimchar suggests that they head to the Wigglytuff guild to seek an answer. Here, Wigglytuff assigns them to be Pokemon Explorers. For their first mission, they have to head into the Labyrinth Cave in order to find a Gabite Scale for a sick Shinx. With a Sunflora tagging along, they head into the dangerous cave.
