Wanderlust World Wanderlust World HorrorLand is not a real theme park. It is a fictional setting created by author R.L. Stine for his Goosebumps children's horror novel series (specifically One Day at HorrorLand and the HorrorLand spin-off series). In the books, it is a sinister amusement park run by monsters ("Horrors") where unsuspecting families become attractions. It has also appeared in Goosebumps video games and the 2015 film Goosebumps, but it does not exist in reality.
