In the games
Torkoal is first met when the player and their partner clear Waterfall Cave for the first time. He tells them to rest in the Hot Spring before going back. Later when the player and their partner are trying to find the location of the Hidden Land, he comes to the Wigglytuff's Guild and tells the Guild about a pattern. After that, he examines the partner's Relic Fragment and tells the Guild that the pattern on the Relic Fragment is the pattern. Later on, Wigglytuff then remembers a similar pattern at the end of Brine Cave, which Chatot, who was with Wigglytuff at the time, also recalls.
Torkoal is the town elder and the wisest of all Pokémon in Treasure Town. He can usually be found relaxing at the Hot Spring, which is where he is found before and after he is asked about the location of the Hidden Land.
