I was in lavender town in the tower and you know how on one of the floors there is that purified part where you heal your Pokemon, well when I reached one of the tiles of it, I was attacked by a ghost then after the battled the purified part healed my Pokemon, so in that bit isn't there supposed to be no ghosts?
Hmmm, It's happened to me. It spooked me, but it's SUPPOSED to be normal. But, at the time I thought my game was glitched and that's why I don't play red anymore.
