Kingdom Hearts 3: 13 Ways To Include Every Pixar Movie

13. Up

Were they to visit a world themed around Paradise Falls, Sora, Donald, and Goofy could come across Carl and Russell at the start of their own adventure. From earning Dug as a party member to battling Muntz - who could be utilizing Heartless in his drive to capture Kevin - Alpha, and the rest of the dog pack, the film's events could play out in a streamlined fashion befitting Kingdom Hearts' typical Disney-related storytelling.

Considering that Carl's past with Ellie forms the huge emotional (and crucial) core of the film - something the game would likely be unable to really explore - it would be understandable if a world based on the film wasn't included simply to retain its integrity. However, giving players the ability to summon a character like Dug or Kevin into combat would be a great fun, and an easy way to honor the movie.
