Sludge Mound

2 Pokémon can be caught at Sludge Mound in Hisui.

Sludge Mound lies in the southern Crimson Mirelands of Hisui, between Gapejaw Bog and Ursa's Ring, and can also be entered from the Bogbound Camp once it is established. Its defining feature is a huge rounded plateau resembling a crater, which forms a natural arena rimmed with dead trunks and set within a thick forest of lifeless trees and ore deposits. The noble Ursaluna, watched over by the Pearl Clan warden Calaba, dwells here and is battled in Mission 8, after which he becomes available as a Ride Pokémon.
