Wellspring Cave

9 Pokémon can be caught at Wellspring Cave in Unova — highlighted on the map below.

Named for the underground wells formed as rainwater filtered through the soil into hidden springs, Wellspring Cave occupies the northwest corner of Unova's Route 3, its stalactites still dripping steadily. The player teams up with Cheren in Black and White against four Team Plasma members here across Single and Double Battles, learning of the group's scheme to take trainers' Pokémon in the name of liberation. TM46 Thief can be picked up near the entrance, but crossing the central pool requires Surf, and the pitch-black lower floor — where Black Belts and Battle Girls train — benefits from Flash.
