Oho Oasis is an island located in Oho Ocean to the east of Beanbean Castle which only appears in Mario & Luigi: Superstar Saga and its remake. While part of the Beanbean Kingdom, the island is not inhabited by Beanish. Rather, the native Oho Jee (both red and blue varieties), Crabs, and Hermit Crabs are the only creatures who live there. Additionally, the Fire Palace and Thunder Palace each serve as a home to one of the island's deities. The Fire Palace is home to Firebrand, and the Thunder Palace is home to Thunderhand.
Prior to Mario & Luigi: Superstar Saga, the Oho Oasis Research Exhibition attempted to study the island and its Oho Jee inhabitants. After accidentally setting a red Oho Jee on fire and witnessing the above phenomenon, one of the researchers was turned into an Oho Jee. The last known recording of them stated that they needed to try an equivalent experiment on the blue Oho Jee. The fate of the exhibition is unknown, but two of their tape players remain on the island.
During the game's story, Mario and Luigi land on this island after falling from an angry Beanstar. The brothers find the two palaces. In the Fire Palace, Mario summons Firebrand and learns the Firebrand technique. Likewise, in Thunder Palace, Luigi summons Thunderhand and learns the Thunderhand technique. Using these techniques, Mario and Luigi light a fire and electrically charge an orb in the offering block, opening a pathway to the Oho Ocean Seabed. Later in the game, Mario and Luigi can return here by crossing Oho Ocean using Luigi's surfboard form.
Bordering or connecting locations to Oho Oasis include:
The island is very small, even smaller than the western area of Beanbean Castle Town. Most of the island is covered with lush vegetation, such as palm trees. The northern portion of the island is solid rock. This is the only side of the island not to have a sandy beach. Three structures still exist on the island: the Fire Palace to the west, Thunder Palace to the east, and the offering block to the southeast. The palaces are on elevated portions of the island and feature great staircases leading to their front doors.
The Oho Jee that inhabit Oho Oasis are found wandering about the island and inside the palaces. They speak openly to the visitors of the island, revealing that their thought process is much different from that typical of other races. Red Oho Jee stay on the western side and inside the Fire Palace while blue Oho Jee stay on the eastern side and inside the Thunder Palace. Attacking a red Oho Jee with Firebrand or attacking a blue Oho Jee with Thunderhand incites them to a battle. Although Mario and Luigi can win the battle, the Oho Jee does not disappear, which means the brothers can fight them multiple times.
