TTar phantom's getting a water type from me.
Edit: you get a Wooper called Irrelevant. It thinks it's a DW Quagsire with Unaware, so every time any Pokemon uses a Stat Up move, you must switch in Wooper (or keep it in if it's already in), and then Wooper must KO it.
Since that's relatively unlikely in game, Wooper also has to solo 10 Gym Leader Pokemon, at least 5 of which must be of a level higher than Wooper's, after which you may evolve it into a Quagsire.
And to end it, you must make sure that your other Pokemon have, between them, at least 3 moves that don't deal damage (this means no Toxic, no leech seed, but T Wave is fine), before you evolve Wooper.
See, I'm not always that mean... ;)
Edit 2: I made Edit 1 within five minutes of posting. :D
Just A1 for short. Apparenlty people can't spell Treadshot.

Note: Yes, it is spelt wrong. Deliberately. Shut up, you're not the first to notice.
