Could've been a Poliwag, Poliwhirl, or Poliwrath.But the weirdest pokemon dream I've ever heard of was one my sister had a LONG time ago. We're talking original G/S long ago. She was in this place with some trees, and she stepped into quicksand, and started sinking. Then it turned out the quicksand was a Muk (she really didn't like Muk back then). Then a white-and-blue pokemon she had never seen before rescued her by attacking the Muk. This was the days of G/S. Many years later, D/P came out, and we found out that the pokemon was Pachirisu. If that isn't the weirdest occasion of telling the future, I don't know what is.
