Methods to obtain

  1. Byte shifting via N Pentamark S.png (00) or N Pentamark S.png (FF) (available through stabilizing a bad clone or arbitrary code execution) (e.g. byte shift a total experience of 254 or 65024-65279; unconfirmed).
  2. ????? party overloading roaming Pokémon manipulation (254 Attack).
  3. Arbitrary code execution (e.g. through 0x15 character arbitrary code execution, TM33 outside of the TM/HM pocket; glitch Pokédex mode 9).


This glitch Pokémon can be safely caught when forced on the opponent's side, and does not have the party cloaking effects that ????? (00) and ????? (FF) have.

It has the 'water Pokémon' menu-sprite used by Lapras.

Additional sprites

The front sprites of this glitch Pokémon may be affected based on the location it is encountered, whether an item was used, and the previous enemy battle sprite.
