In November of 2012, various passwords for downloading the three monkey Pokémon Yanappu, Baoppu and Hiyappu were published. Each of the three Pokémon could be downloaded once per game after the password is entered. The event ran from November 15th 2012 to January 10th 2013, and was only accessible for Pocket Monsters Black 2 and Pocket Monsters White 2.


The password for a male Yanappu with the Hidden Ability Overgrow and the egg move Leaf Storm was posted on the official Daisuki Club site November 16th. The password was: しんりょくリーフストーム.
