Plot
Bowser & Jr. discovers a portal that leads to a parallel universe with an alternate timeline, where he finds that he is an animator for Disney, a dream he has always had, because of a chain of events starting when he was chosen to star in a Pops commercial when he was a child.

Because in his current universe, he didn't fet the part in his commercial and thus didn't become an animator, he travels back in time to change this, messing up the timeline and putting the space-time continuum out of whack. He must now work together with an unlikely group of friends to save the universe before all of creation ceases to exist.
