TM024 (Japanese: わざマシン024Move Machine 024), known as TM24 prior to Generation IX, is a TM introduced in Generation I. It teaches a compatible Pokémon a move. The move it teaches depends on the game. For compatibility, refer to the move's page.
TMs in the Mystery Dungeon series are named only by the move they teach. For example, Attract is the item that teaches the move Attract. Most TMs, however, correspond to a TM in the core series' contemporaneous games.
In Pokémon Crystal, it is possible to obtain two copies of TM24. If the playerwhites out due to poison damage while still inside the Dragon Shrine in Dragon's Den after receiving the Rising Badge, they can return to the Blackthorn Gym to receive the reward TM from Clair. However, if the player then returns to Dragon's Den and stands on the tile directly in front of the Dragon Shrine's door, Clair will appear again and give the player another TM24.
