Swapping Transform moves glitch

The Swapping Transform moves glitch is a glitch in Pokémon Red and Blue. It was fixed in Pokémon Yellow.

If the player switches the positions of two of a Pokémon's moves after transforming (via the Select button), then the positions of its real moves will be swapped after the battle.

Obtaining the CoolTrainer move

See CoolTrainer♀ move for more information.

If the user's Pokémon has less than four moves, then the CoolTrainer♀ move ("-") is available.

The easiest way to do this is to obtain a Ditto from e.g. Route 15 (east of Fuchsia City), then encounter a wild Pokémon with more than one move. Swap the 2nd, 3rd or 4th move with the first, then at the conclusion of the battle the first move will be replaced with "-".

After obtaining the CoolTrainer♀ move it may have 0/13 PP at first, and healing at a Pokémon Center won't restore its PP. However, if the player uses a certain PP restoring item (Ether or Max Ether only), it's possible to use the move.
