Princess Peach knows a lot about the Mushroom Kingdom. More than the Mario Brothers know, in fact. For example, she knows that taking a certain Warp Pipe will transport anyone in it to another magical kingdom that's filled with talking horses. So when she invites the brothers on a trip to a "special place," the Marios eagerly accept. Upon being transported away through the Rainbow Warp Pipe, they end up in Equestria. Peach goes off to talk about royal matters and have a casual conversation with her old friend, Princess Celestia, while the brothers stay in Ponyville.

This peace is short lived, as it usually is. Bowser has a tendency to show up at the worst of times. Using his dark magic, he creates a barrier around Canterlot that traps everyone inside and lifts it into the stratosphere. And for good measure, he destroys the Rainbow Warp Pipe and and send the only things that could stop him back into the Mushroom Kingdom: The Super Mario Brothers and the Mane Six.

What Bowser plans to do is unclear, but one thing is certain: even though he's in a separate dimension, the group of adventurers are still in over their heads, because old, familiar faces are coming back to haunt the Marios.
