Magma Castle

The Magma Castle is the front-right fort on Bowser's Castle in Yoshi's Story. Lava here is transported through Bowser's Castle, causing falls and geysers. Enemies encountered include Spikes, Lava Bubbles Puffers, Barbecue Guys, Attacky Sacks and even a red dragon. A Slug is also found in the tower.

Layout
The level starts near a Dragon which must be ridden in order to collect some fruits and advance to the next area. Here, lava comes out of pipes and Yoshi must traverse some moving platforms, while avoiding the lava, in order to get to an area with more lava and narrow corridors. After the player collects thirty fruits, the battle against Baby Bowser starts. Yoshi must hit Baby Bowser three times with spikes by throwing Bob-ombs he gets from the Super Happy Tree and knocking them off the roof, in order to make him jump to ground level. He must repeat the process on the ground three more times to finish the level and beat Baby Bowser. If the Yoshi runs out of eggs before he beats Baby Bowser, then he can eat the fruit on the tree.

''The Yoshis found the castle and figured the Super Happy Tree was there. Instead they found hot lava and a hot-tempered Baby Bowser. But happiness wins in the end, and the Yoshis battled Baby Bowser.''
