Don't Fear the Spear
From the Super Mario Wiki
Yoshi starts the level in a jungle-like area with an Egg Block and some Spear Guys. Soon after, the player reaches an area with Petal Guys masked as flowers and an area where Poochy must be used to get a key and open a locked door. It leads to the Middle Ring and another area with moving platforms with Spear Guys on top of them. The Yoshi must traverse the area and eventually reach the goal roulette.
