Here's my opinions of our new starters.
The Grass one, Tsutaja, would have to be my favourite. It almost reminds me of Cyndaquil mixed with a Treecko. It's more cool looking than cute. They did good with this one.
The Fire one, Pokabu, is 2. Even though it's a Pig, it only gives up foresight on it's awesome evo's that might come up. It looks cute, as well.
The Water one, Mijimaru, Is terrible IMO. It looks like a more drab version of a Piplup mixed with a Mudkip. I wouldn't judge this Pokemon so soon as it's exo's may be better. Then again, I probably won't use this one...
