2ch, others leak heap of Black and White info
Previously uploaded images from 2ch have shown possible evolutions of Tsutarja, Mijumaru, and Pokabu. There is also information suggesting that Yanappu is part of a larger group of gimmick Pokémon known as the "Monkey trio", featuring a blue monkey known as 「ヒヤップ」 Hiyappu, speculated to be a Water- or Ice-type, and an unseen monkey called 「バオップ」 Baoppu, who is suspected to be a Fire-type.
The evolution images had been previously shown on the 2ch imageboard on Wednesday, and their legitimacy has since been heavily disputed by the fandom. As such, please keep in mind that though Bulbanews is running the story, there is no definite confirmation as to their legitimacy.
More information will be revealed as it comes.
