Corona Mountain is the eighth and final level in Super Mario Sunshine. Corona Mountain is a volcano on Isle Delfino, located directly behind Delfino Plaza. As Isle Delfino is shaped like a dolphin, Corona Mountain is placed where the dolphin's blowhole would be. The entrance to the volcano is located behind the Shine Gate, over a couple of ledges and behind a hot spring. To enter Corona Mountain, the player has to have had completed each of the other levels' seventh episode, which are the Shadow Mario episodes. Upon doing so, the gate blocking the entrance to the volcano will break and Delfino Plaza will become flooded. Simply entering and leaving Corona Mountain will return Delfino Plaza to normal.
Super Mario Sunshine
The interior of Corona Mountain is a large pool of lava with several scattered platforms. Several of the platforms appear to be part of a broken walkway that used to lead to the back of the volcano. The first half of the volcano has large, square platforms Mario has to jump between. The platforms contain either spikes that move in and out of the platform or fire that Mario has to spray with F.L.U.D.D. to dowse. Several Lava Cheep Cheeps will also be jumping out of the lava in the first half of the stage. In the center of the stage, there is a sprinkler players can use to refill F.L.U.D.D. and a crate with a 1-Up Mushroom in it.
The second half of the stage has many spires coming out of the lava and the player needs to use a boat to move through them to the platform in the back. To propel the boat, players have to spray water in the opposite direction of where they want the boat to move, though the propulsion also takes into account where Mario is standing on the boat. If the boat crashes into something, it will sink and Mario could fall into the lava. In the center of the spires is a sprinkler that will refill F.L.U.D.D. if Mario travels underneath it.
At the end of Corona Mountain is a large, circular platform with a Rocket Nozzle power-up. Using the Rocket Nozzle, Mario can shoot up to the clouds above; at the top is a red cloud that will send Mario to the final boss fight when he shoots through it.
This location contains only the following episode. Despite this, there is an unused banner for this episode, meaning it was intended to have an episode selection; the Shine Sprite collected after the level is counted as a Shine Sprite for Delfino Plaza.
Blue Coin Locations
Ten Blue Coins are found within Corona Mountain. One is found on the stone platform in the first half of the stage, and the other nine are found above the lava in the second half.
Mario Sports Mix
Corona Mountain appears in the premade world for the Super Mario Mash-up in Minecraft. In this game, it is located in the Extreme Hills biome, and the end of the level section has a Music Disc.
The hot spring at the foot of Isle Delfino's mountain is relaxing, but the lava caves, which open on the plaza, are forbidden for public safety.
"Corona" means "crown" in Italian, Spanish and Latin, and can also refer to the superhot plasma atmosphere that surrounds the sun. Because the rest of the locations of Isle Delfino have Italian names, the lava-filled volcano's allusion to the sun's heat may have merely been an afterthought or coincidence when "corona" was chosen for the mountain that crowned the "head" of the dolphin-shaped island.
