- Six of these levels, that is, Red Lava, Orange Prairie, Yellow Beach, Mossdeep Greens, Blue Chilldesert and Navyblue Molemine all have inaccessible secret exits that may be linked to the unused Special World. It may also be likely that these secret exits were required in order to move on to the next level.
- It is unknown if the other four levels in this world were intended to have secret exits.
