Okay, so I'm doing a Nuzlocke on Pokemon Emerald, and I caught a Wurmple at level 2 and it died at level 4. It doesn't know any HM moves, so why can't I release it? I've also heard that if a Pokemon has maximum happiness, it also can't be released. But I only had it for two levels! What's going on? Is it possible that it reached maximum happiness in such a short time? Please answer. Thanks!
