Lavalava Island

Lavalava Island is an island in Paper Mario and is the holding place for Misstar, the fifth Star Spirit. Jade Jungle, Yoshi's Village, and the volcano make up most of the level. Raphael the Raven and Sushie live here, and after Mario helps Sushie find 5 missing Yoshi kids, she joins him on his quest to save Princess Peach. Unfortunately, while Mario and his comrades visit the island, something's happening in the volcano, Mt. Lavalava, and it's a tough journey through that lava-infested place. The boss is Lava Piranha and two Lava Buds.

According to Russ T., who lives in Toad Town, Lavalava Island used to be home to humans long before Yoshis and Ravens arrived. He claims that the humans used to live in Mount Lavalava's various outside caves. He can confirm this by the artifact that Kolorado found there.

About the Boss
Lava Piranha is a giant Piranha Plant that won't give up. Even when you think you've beaten him, you haven't. You'll have to face him twice. The second time, he's on fire and has gained more power. Make good use of the shields your allies can make for you, because they get powerful. Have your fire shield equipped and also any ice badge, except for the Ice Shield. You won't need that. Here's a hint: take out the two Lava Buds first, and use Sushi's water techniques when there's fire on Lava Piranha's head.
