The episode starts with Toadsworth explaining the Superstar Mashup, which occurs every year when the planets align, with in typical fashion Mario saying that it's boring. Luigi then says he shouldn't say that legendary is boring. Then Mario says that this stuff is "Hocus Pocus" and probably won't happen for years. To Mario's surprise, Toadsworth says that it will happen tomorrow. Mario was shocked and said it probably won't happen tomorrow either.
After that, Mario is there a day later saying why is everyone dragging him here. With Peach replying that the Superstar Mashup is happening. Mario then says that it's probably not gonna happen. Then he counts to three hoping that it won't happen but ultimately fails and the castle shaking in the process. 
The castle then stopped shaking to reveal that the path to Sonic's world actually opened up. Mario was surprised this happened, and everyone started dancing behind him as a victorious music played. Mario and Luigi then crossed the path but fall because of a crack in the ground. They fall onto a forest, where they find their way through bushes and trees to find Sonic and Tails exploring the forest. Mario says they look like enemies, but Luigi thinks they look kind and nice. Upon Mario saying they shouldn't draw attention, with Mario stepping on a branch. Mario and Luigi get tied up in a rope. 
Sonic asks them who sent them, with Luigi saying the Mushroom Kingdom did. Tails realizes that they're the heroes that come from the Superstar Mashup. Mario says stop talking about the Superstar Mashup before he hits him in the head. Sonic says don't talk to Tails like that with him rudely replying that he'd know that. Luigi says that they shouldn't get to hasty. With Tails replying that they should go home now. But then, the planets collide with Toadsworth saying that this rare event happens where both planets collide.
