That arm and that tail belong to Yannapu.
Still hope that, even being "real", they are beta versions. I hate Pokabu's second stage, it looks awful. The third I can chew, but it is far from living to my expectations. Like most of the people, I was expecting something quadrupedal and awesome. As for Tsutaja, I like the evos, but I'd change the second one a bit, to make the transition to the third stage smoother, without ruining it's resemblances to the first stage. Mijumaru, where to start? I'd like that Mijumaru's second stage was white, like him. It's way cooler than Mijumaru, though, even if it's weird-blue, and as for the third stage: KILL ME! That's awful! The only way to make it kind of cool, would be for it to match that deviantArt fan art that's on the first post, but I've seen fan arts way cooler than the "official" third stage.
That's all.
