Route 126 is a large, circular area with a dormant volcano at its center, the home of all Sootpolites. There is a multitude of trainers to battle and items to find, but you can do that later - you've got a Region to save! To continue the main story, head to the southern part of the route and use Dive on the dark patch, and enter the cave you find underneath.

Relicanth is found underwater in Route 126. Though it is a fish Pokémon, it cannot be caught with a fishing rod. It is slightly tough to catch; 2 or 3 Ultra Ball s might get wasted, and Net Ball s and Dive Ball s do not work well.
Along with Wailord, Relicanth needs to be present in the your team to remove the seals from the hiding places of the Legendary Pokémon, Regirock, Regice and Registeel. To see more detailed information on this, see Capturing the Regis.
