Eevee needs to post.

Oh, what if you forget to feed your Eevee?

1) It gets a terrible sickness and evolves into Toxeon (poison type :D!)
2) It dies, you bury it and evolves into Bansheon (ghost type :D!)
3) It dies, you take it to PKMCTR and they evolve it into Geareon (steel type :D!)

Other evolutions:

Use too much stat-gaining items on your Eevee: Taureon evolution (imagine an centaur-eevee with extra buff arms and chest.) Fighting type.
