There are HUGE amounts, but all mostly look the same. The most infamous being of Missingno., who can be caught in Pokemon Red, Green, Blue, or Yellow. Talk to the man in Viridian City, the, as quoted, "OLD MAN," and ask him to show you how to catch Pokemon. after that, FLY to the island at the very bottom left of the map (Sorry, but i forgot the name.), then, SURF up the 4 tiles on the island. !!!!WARNING!!!! THIS CAN PERMANANTLEY GLITCH UP YOUR INTERNAL BATTERY, PROGRAM MEMORY, ETC!!!! HE WILL REMAIN ON THE CARTRIDGE EVEN IF YOU DON'T SAVE!!!You neeed a hack device for this glitch I'm about to tell. Also, he's not much of a pokemon, but...a trainer. Yes, he's BURIED ALIVE!!!! This was a *Ahem* Trainer *more like zombie* left from the beta,but he was removed, so someone had hidden it! But
