Based on Mario and Luigi: Partners in time. One of the scientists has just discovered a way to travel between the timelines throughout Equestria. Princess Celestia along with two other ponies have been selected to go on a test run. However, the past doesn't seem to be right. It is now being invaded by an alien race known as the Shroobs and Princess Celestia has been captured. Can Applejack, Rainbow Dash, and Rarity fix the past and save the princess?

Inspired by DryvernX's story Twilight and Rarity Partners in Time.

We have our host Discord, along with his co-host Fluttershy hosting a race through different universes, and the real world to win the grand prize of 500000. 14 teams from Equestria, 9 from the Mushroom Kingdom, and one mystery team will be competing. Who will win it all?

This is similar to Starlight Fan's story "The Fantastic Crossover Race", but he was inspired by my original one on my Fanfiction.net account.

Note: This takes place right in between the finale of Season 4 of My Little Pony and after the events of Rainbow Rocks.

Enjoy!!
