Wild ♀ . can be found in the Yellow version by doing Method #3 of the Mew glitch with a Pokémon with a special stat of 193. It can also be obtained by trading a ゥ (C1) from the Red/Blue versions to the Yellow version. The Pokédex number for ♀ . is #205, this means that this glitch's National Pokédex equivalent is Forretress. It is worth noting that this Pokémon usually freezes a player's game when it is encountered using the Mew glitch due to its long cry (its length varies from encounter to encounter; some players have used emulators to speed it up but none have reached the end of it, so it may just be a continuous loop). Its Red/Blue equivalent, ゥ, also freezes the game. On rare occasions, ♀ . may appear without freezing. It is reported that the player is unable to see what moves ♀ . is learning or what attack it is going to use, since it covers the text box with black.
When ♀ . appears in color in Pokémon Stadium, the Pokémon itself will be red and surrounded by a black square. This is the same as the square surrounding Glitch (CA).
♀ . has the longest cry of any known Pokémon, regular or glitched.
