Hidden Grotto (Japanese: 隠し穴 Hidden Hollow) is a feature introduced in Pokémon Black 2 and White 2 that allows the player to catch Pokémon that have a Hidden Ability or find items. The contents of the Hidden Grottos are random, and if they are empty, for each 256 steps, they have a 5% chance to regenerate, usually with different content than what was inside on the previous visit.
