Mt. Lavalava is a volcano on Lavalava Island in Paper Mario. As the main part of the chapter, it is where Mario finds the fifth Star Spirit, Misstar. It is also the home of the vile Lava Piranha. The Ultra Hammer is found here. Kolorado accompanies Mario through most of the volcano, but he's not interested in searching for a Star Spirit; rather, he just wants to follow Mario to get the treasure hidden in the volcano containing a Volcano Vase.
Between Chapters 4 and 5 of Paper Mario, Mario learns from Twink (who learns from Gourmet Guy when accompanying Princess Peach) that a Star Spirit is being held in Mt. Lavalava of Lavalava Island and seeks to go there. In the meanwhile, he finds Kolorado by the Toad Town port, who is also hoping to travel there in order to find a legendary treasure. The two eventually travel to Lavalava Island with the help of the Whale.
In Chapter 5, the two initially see the entrance of Mt. Lavalava, but are blocked by a lava pit. After a series of events, Mario and Kolorado make their way to Mt. Lavalava with some ropeways built by Raphael's Ravens. Upon their entrance, Mario is identified by a Piranha Plant who then shouts "ALERT" and "REPORT TO BOSS". As the two proceed, Mario does most of the exploration, clearing Metal Blocks with the Ultra Hammer found inside the volcano, while Kolorado suffers various injuries while trying to be useful and even leads Mario to the wrong way at a spot. Deep in the volcano, Mario is identified by another Piranha Plant as searching the Star Spirit, and encounters Lava Piranha, the chapter boss. Mario defeats it, and saves Misstar. This marks the end of Chapter 5.
At the same time, however, the volcano begins to erupt and their way back to the entrance is blocked by a lava-filled gap. Near the caldera, Misstar finds a cracked wall and Mario blows it up with Bombette. At the moment of life and death, Kolorado is still reaching for a treasure, while Misstar quickly carries Mario, his partner, and Kolorado and flies upward through the caldera. Eventually the four escape the volcano narrowly, and the treasure chest containing the treasure is blown out of the mountain and falls in Jade Jungle. Kolorado, chastised by Misstar for not valuing his life, eventually gets the treasure from Mario and proclaims the adventure a "complete success", a "stupendous expedition" which will be "forever recorded in the history of archaeology".
The Village Leader of Yoshi's Village states that Mt. Lavalava erupted because of Bowser's men at work . Later in the game, there is a piece of news covering the eruption, which says the same thing but cites Kolorado. Mario also receives a letter from the Yoshi kids in Yoshi's Village, which says that Mt. Lavalava stopped erupting and invites Mario to the village.
