The original concept for Beastly Kingdom would have divided itself in half, with one part of the land dedicated to “good” animals, like unicorns, and the other half focused on “evil” animals, like dragons. There would have been three significant attractions in the land. The “good” side would have included a boat ride called Fantasia Gardens that took guests through a musical adventure from Fantasia. The other attraction there, Quest of the Unicorn, would have been a maze for guests to wander through, with a magical, animatronic unicorn at its center.
