No.592
Got to the chocolate world, either from the forest world, or from the movie theatre. Find the thing that looks like a yellow sphere with some purple stuff around it, talk to it, and you'll be teleported to the stone maze. Equip the fairy or the spacesuit effect to fly over smaller gaps, and find the red bowling ball. Talk to it, and you'll be at the bowling alley. From there, follow the wiki.
