(Variable name) is a false Normal (0x0C)-type glitch move in Pokémon Red and Blue. It is capable of causing Super Glitch.
Successfully using this glitch move without significant Super Glitch corruption (possible by having a 0x50 sub-tile early in the saved screen data) may result in damage with Growl's animation.
As a side effect, this glitch move may also raise the user's glitch stat 0x5D by two stages, or display the message "Nothing happened!" after the damage has been inflicted (if the move does not faint the opponent).
