Fan Casting Disney's Wario World (2021)

Wario enjoying his newly built castle, which is filled with treasures that he has collected from earlier adventures. An evil gem called Black Jewel, hidden amongst Wario's treasure collection, suddenly awakens and takes over Wario's castle. Black Jewel turns Wario's treasure into monsters, and transforms the castle into four worlds called Excitement Central, Spooktastic World, Thrillsville and Sparkle Land, each consisting of two levels and a boss fight. A central area allows access to the different worlds, as well as to the Treasure Square, where the Huge Treasure Box inside of which Black Jewel is hiding can be found. Wario proceeds through the areas controlled by Black Jewel, recovering his treasure and rescuing Spritelings (the creatures had sealed Black Jewel away in the past), then obtains the key to the Huge Treasure Box and engages Black Jewel in a battle. Wario's subsequent victory allows him to regain control of his castle. Wario's new castle quality depends on the number of Spritelings rescued. The worst-case scenario sees Wario with nothing but a campsite with his throne in a dark jungle, but if all 40 Spritelings were rescued, Wario is given a palace even grander than his previous one.
