Starters

[Jeff]

Left one: Probably the grass type. That looks like a leaf on its tail.
Middle one: Looks like a cross between a pig and a rabbit. I'm guessing fire, because it fits with the pattern grass-fire-water and because...
Right one: It looks like it has an innertube around its neck, so that's probably our water starter.

@Jeff: As soon i saw the left one i though of Charmander but you got a point there. (It reminds me of Moomins XDD)

The one in the middle looks like a Pikachu-Spoink-Turtwig combination O.o The right one is like a Mew-Piplup meets bidoof? Because of its tail.
