Sea Mauville

8 Pokémon can be caught at Sea Mauville in Hoenn.

A decrepit research platform north of Route 108, Sea Mauville stands where Ruby, Sapphire, and Emerald placed the Abandoned Ship. The location covers the crumbling structure itself along with the surrounding water and a sandbar; Dive is needed both to enter the submerged second section, which holds the Scanner, and to travel through the interior to the northern exterior.
