Lavalava Island

Lavalava Island is an island in Paper Mario and is the holding place for the fifth Star Spirit. Sushie lives here, and after Mario offers helping her find 5 missing Yoshi Kids, she joins him on his quest to save the Star Spirits and Princess Peach. Unfortunately, while Mario and his comrades visit the island, something's happening in the volcano, Mount Lavalava, there, and it's a tough journey through this lava-infested place. The boss is a Lava Piranha and two Lava Buds.

About the Boss
They are giant Piranhas that won't give up. They are tough, especally when you take them out. Even when you think you've beaten them, you haven't. You basically have to face them twice. The second time, They're on fire and gain 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 the Lava Piranha's head.
