It looks like Bowser has another plan to kidnap Princess Peach...again. But, it looks like his plan will succeed when he does the unthinkable: stealing a mystical wand called the Star Rod, said to grant any wish to anyone who holds it, sealing away the Star Spirits, 7 powerful star beings that watch over the land and grant wishes to those with a good heart, and using the Star Rod's power to take over the Mushroom Kingdom, defeat his nemesis, Mario, and make Peach his.

Meanwhile, in Equestria, Twilight had managed to come up with a spell to transport to other dimensions without the use of a portal. Eager to try it out with her friends after her experience in the human version of Equestria, and a few experimental tests with other objects beforehand, she casts the spell to transport them, only for it to backfire, sending them into the Mushroom Kingdom. Stuck in this new world until Twilight can find a way to safely get her and her friends back home, the Mane Six will have to team up with Mario and new friends in this new world to stop Bowser and save the Mushroom Kingdom from his tyranny.
