Whiscash resides in Whiscash Pond and is first met there. He enjoys telling stories and is the first to tell the player and partner of the Ninetales legend. Whiscash is seen in Whiscash Pond throughout the whole game. He is the wisest Pokémon in Pokémon Square, and the second wisest in the Pokémon world, second only to Xatu.
After the ending credits, he gives the player the HM Dive, which enables entrance to Stormy Sea. He also unlocks Solar Cave, where HMs Waterfall and Surf can be found. A replacement Dive can also be found there.
Whiscash appeared in Pokémon Mystery Dungeon: Team Go-Getters Out of the Gate!. Like in the games, he resides at Whiscash Pond. Whiscash was first seen trying to comfort a Pichu whose older brother Pikachu had gone missing in Sinister Cave. He told Pichu that Team A.C.T. would save Pikachu, but Snubbull told him Team A.C.T. was already on a mission. Just when it seemed there were no other Teams available to rescue Pikachu, the newly formed Team Go-Getters and Team Meanies showed up. Whiscash agreed that both Teams should go and rescue Pikachu.
