Hot Spring Island

Hot Spring Island is a location in the Seaside Kingdom in Super Mario Odyssey. It is an island located in the northeastern part of the kingdom.

When first visiting the island, it is covered in lava, which can be removed if Mario captures a nearby Gushen to spray water. This allows him to collect the Power Moon for The Hot Spring Seal and unlock a Ground-Pound Switch needed to release a fountain. Upon defeating Mollusque-Lanceur, the island returns to normal, with two Bubblainians appearing on it; after completing the main story, more visitors from different kingdoms come to visit Hot Spring Island. Besides the Power Moon, a Checkpoint Flag and several regional coins can be found on the island.
