I've always wanted a dolphin-based water type. There's so much potential for absolute brokenness. Well, starters have never been broken, but a guy can hope . . .
Think about it, for a dolphin the following would all be within logic:
Water / Normal typing, maybe I'm stretching it here but we've got Bibarrel and Dolphins are mammals like Tauros and friends-- it's not impossible . . .
If you had Water / Normal, also consider that a dolphin would likely get the following:
-Water Spout
-Hyper Voice
If you don't get where I'm going this, I'm sorry for you really . . . but in short, echo-locating animal with a blow-hole gets near-flawless dual-STAB coverage with a 150 base STAB attack with one of the best primary offensive types in the game.
Plus, dolphins may not be the fastest animals in the sea (oddly, penguins are, poor empoleon), but I'd assume we could expect a pretty good speed stat with that too.
Well, this is all random speculation, but I think that would be bad-ass. I'll just got the extra-mile in my stupid-fanboy speculation and say:
Water / Normal
