Hidden Grotto (Japanese: 隠し穴 Hidden Hollow) is a feature in Pokémon Black 2 and White 2 that allows the player to find Pokémon with Hidden Abilities or items. The contents of the Hidden Grottoes are random, and if they are empty, for each 256 steps, they generally have a 5% chance to regenerate, usually with different content than what was inside on the previous visit; however, the chance can be increased with the Hidden Grotto Pass Power. Hidden Grottoes will not regenerate unless the items are obtained or the Pokémon are caught or defeated by the player.

Pokémon

The chance that a Pokémon will be spawned when a Grotto is regenerated is 20%.

Pokémon that appear in Hidden Grottoes have non-standard gender distribution rates, and the gender of the Pokémon is predetermined and cannot be soft resetted for. Those species that are gender unknown, all-male, or all-female are unaffected. Most of the rest will be female 30% of the time, but Clefairy, Corsola, Minccino, and Pachirisu will be female 60% of the time, Dragonite, Poliwhirl, and Vulpix will be female 10% of the time, Combee will be female 5% of the time, and in White 2 Nosepass will never be female.
