Torrential Maze is Stage 2-4 of Yoshi's Story. The level is composed of a labyrinth of water and is flooded with spikes, jelly, and extremely fast moving water. Enemies include Spiked Fun Guy and Vine Slime. It seems to be part of Jelly Pipe because of its background and the fact that jelly exists there.
Black Yoshi can be found in this level. In Story Mode, the player should travel to the area with the third Miss Warp. From there, the player must go all the way to the area with the vines. Avoiding the Vine Slimes, the player needs to climb and jump from vine to vine to reach an alcove above the dead end. On the right side in the alcove is a ? Bubble, which the player needs to pop to reveal and collect the black Yoshi's egg. The player needs to finish the level with it to unlock Black Yoshi.
To avoid a dark, scary cave, the Yoshis entered a nearby tunnel. Inside, they found a maze that overflowed with rushing water. Perhaps they should have just gone through the cave instead!
