Chespin: Maybe pure grass? I'm not sure what kind of animal Chespin is.
Fennekin: Fire/Dark, Fennec Foxes are nocturnal... but so are most owls and I don't see a dark typing on Noctowl lol. Lol, still though, Fire/Dark just for lols in breaking Fire/Fighting by making it something weak to the previous ones.
Froakie: Water/Fighting, Water/Dark or Water/Ice.
