Unlike Fairy World, which is bright and pink with a colorful purple sky, Anti-Fairy World is dark and blue with a blood-red sky. The Anti-Big Wand and other buildings in this world are twisted and vile looking. The ruler of this world is Anti-Cosmo, who resides in a giant Gothic-looking castle.
The clouds that Anti-Fairy World resides on are usually blood red and black storm clouds. All of the structures around Anti-Fairy World are twisted and evil looking. There is a purple tinted rainbow that bridges Anti-Fairy World toEarth. It seems to have thorns covering it, possibly to keep other people out. The Anti-Fairy World sign is made of wood and the words are yellow. Anti-Fairy World was briefly turned into a sweet happy world that was covered with niceness and cuteness when Foop redesigned the world for his own amusement after draining out the Anti-Big Wand's Power. It is later reverted back to normal by Foop's crying along with the other worlds that Foop terrorized in his rampage.
- Anti-Cosmo's castle is the place of Foop's birth.
