I like the Japanese names far better, but these aren't so bad.
Oshawott actually sounds pretty cool,
Snivy is okay,
Tepig is [insert explicit and vulgar term for "bad"]!!!!
Hopefully Pokabu's (I refuse to call it that "name") fully evolved form's name isn't "Wreggy" (wrestler+piggy), but something like that is what I'm expecting.
Unova hurts me, it sounds like an Innovator's name (not really, but you get the point: screwed up.). Isshu sounds infinitely better.
