Entrance from the bottom-right wisp
The Cloud Tops is a medium-sized scrolling world filled with many paths made out of the clouds, as well as clouds with faces most resembling emoticons. The clouds with faces will make noises when walked on.
Four different versions of this world can be accessed: One, from the bottom-right wisp in the Cloud Floor, is fairly toned down and has normal- speed music. Another, if you interact with the top-left teleport wisp, is brighter with sped-up music; the third, sepia with hints of other colors, is accessible from the yellow-red room in the Butterfly Forest, and the last, dark as if in nighttime, can be accessed from the isolated platform in Constellation World.
If you travel east-southeast of the entrance wisp/butterfly in either version accessible from the Cloud Floor, you can find a hole in the clouds, apparently displaying a view of the endless void. Jumping into this hole will take you to one of two worlds: the balcony at the School, if you're in the brighter version of the world; or, Neon Candle World, if you're in the less saturated version. Strangely, this hole is nowhere to be found in the sepia version of this world, and in the dark version of the world, it has a 50% chance of appearing. If it does appear, it will lead the player to Geometry World.
No matter the version, there is a painting on a easle, greatly southeast of the entrance, that drops you off right in front of the cloud painting in the Art Gallery.
- Upon returning to the Cloud Floor from the less bright version of this world, the colors will remain toned down and blueish until you exit Cloud Floor to the Red Lily Lake, Candy World, or Chaos World.
- Upon returning to the yellow-red room in Butterfly Forest from the sepia version of this world, the colors will remain orangeish until you exit the yellow-red room.
- Upon returning to Constellation World from the dark version of the world, the colors will remain dark until you exit the area into Candy World.
