There are some rumors going around. Some of it is from GameFAQs and some of it is from PokeJungle. The sources are pretty sketchy obviously, but I thought I'd post it here just in case. A lot of the rumors are the same from both sources, but I've seen the PokeJungle guy post at GameFAQs so it's very possible he just took the GameFAQs stuff and added onto it to get hits. Regardless, here it is...
- Nezumimi is the green monkey Pokemon that weve seen the toy of.
- Nezumimi evolves into Nezumidori, who has a tree coming from its body.
- Jiari is an ant like Pokemon.
- Nenuzura is another bird Pokemon.
- The unknown Pokemon from the anime concept art leak and the toys is Namakusu.
- Namakusu evolves into Ononokusu.
- Karakusu is a Pokemon that resembles a marionette and has eyes like Banette, and could possibly be a Banette evolution.
- Tsutaja evolves into Tsutawaiya (ツタワイヤ

, and the black dress Pokemon is Goshikkuro (ゴシックロ

.
If you're wondering which is which, the ones with the Japanese names next to them are from PokeJungle, while the rest are from GameFAQs. Like I said, probably fake considering the sources, but interesting nonetheless.
