Cool Pokemon concept I thought up.

I saw a year old thread here about the idea of a triple-typed Pokemon, and how if ever such a thing would exist, it would probably need to be a one-off thing like a legendary. So what I came up with was this: a Grass/Fire/Water type pokemon that doesn't evolve, but instead lays eggs that hatch either a Grass, Fire, or Water type pre-evolution that would then proceed to evolve to second and third stages ala starters. Bonus points if these actually became starters of a new gen. Double bonus points if the legendary Pokemon doubles as the regions Professor. Yea, I went there.
