Layout
The level begins near some lava, so the player has to use the bridges nearby to navigate the level. After avoiding some Ball 'N' Chains, Gooey Goons and some lava patches, the player has to go down a nearby pipe to advance. Inside the new area, Yoshi must avoid some Gooey Goons and lava to reach the Middle Ring. Nearby is a Stork Stop, an Egg Block, and a wind gust. Following that is two doors, one of which is locked, and the other one which contains a treasure area containing a Character Coin. Yoshi, paired with Baby Peach, must ride the wind gust to obtain the key to the locked door. Yoshi has to avoid a few enemies, including a Gargantua Blargg, while backtracking to the door. A pipe leading to another secret area can also be accessed there. When near the door, the player should open it, revealing a Haunted House-themed area infested with Gooey Goons. The boss, Gilbert the Gooey appears after this; a huge beige Gooey Goon covered in twenty spheres. When Yoshi removes all of the spheres, either by throwing eggs or eating them, the boss turns red and blows up.
