Xbox One gamers who have watched Frozen are now calling for Square Enix to add in both Elsa and Anna to the upcoming Kingdom Hearts 3, Monitoring Crunch reports.

"Adding Frozen into Kingdom Hearts 3 won't be much of a problem for Square Enix. This is due to the character model which is on the same wavelength. Thanks to this, re-creating the character is unnecessary," the website writes.

"Frozen is definitely one of Disney's finest works. One fan got so into the film that a video got created suggesting the best Frozen music for Kingdom Hearts 3."

YouTube user BlueNctrn has reimagined the Kingdom Hearts 3's soundtrack and offers some of the best remixes you'll hear of Square Enix's upcoming game, Gameranx.com reports, leaving many fans wondering if the developer will consider implementing them into the game.
