WendiWorld was based on characters named Wendi, Jessiebell and Erik. Two areas of the park were StoryLand and TravelLand. Some of the attractions included Jessiebell's Castle and the Dragon's Maze. Food served at the park included spaghetti carbonara, candy floss and Diet Coke.
WendiWorld had its own website.
