Tsutarja, Pokabu, and Mijumaru? No more! Still calling the region Isshu? Time to get an update! You ready?
Snivy, Tepig, Oshawott are the names of the grass, fire, and water Pokemon respectively. Not too sure how I feel about the Mijumaru's English name, but I like how fitting Tsutarja's name. Oh, and Isshu is now Unova, which the awesome people at PokeBeach translated roughly to "One New" from the latin words "Unum" and "Nova". Cool right?
Snivy seems to be a mixture of snake and ivy, Tepig is tepid (which means warm) and obviously pig. Oshawott...I have no idea. The "wott" could be both water and otter, but I'm not sure about the Osha.
