When they got to Canterlot, There was an army of Goombas and Koopas was there to greet them.
"What are those things?" asked Twilight.
Mario and Luigi explained what Goombas and Koopas were.
"OK then, how do we beat them sugar-cube?" Asked Applejack.
Mario and Luigi told them that the best way to beat Goombas and Koopas is to jump on them/use a Koopa shell and kick it back at them.
Then The Mario Bros. and the Main Six jumped/kick the Koopa shells untell all the Goombas and Koopas were gone.
"That was.... AWESOME!" said Rainbow Dash.
Then they whet to Canterlot Castle to see Princess Celestia, But when they got there the Castle was capered by Bowser and Discord. So they whet inside and kick some flanks/buts untell they got to Bowser's Room.
"Well If isn't my old friend Mario, Green Stash and the six pones must be the herons of Equestria." said Bowser as the the gang walked in.
"So the Humans must be the Mario Bros. you told me about Bowser." said Discord
Before Bowser and Discord made the first, the Main six used the Elements of Harmony on Discord and the Mario Bros. The Power from the Elements gave Mario and Luigi star power. Discord turned into stone and the Mario Bros. beat Bowser in no time flat.
After they freed the Princesses, Pinkie Pie throwed a party to celebrate. the Princesses talked about becoming alies, Mario, Luigi and Twilight talked about each others worlds. After the Party was over Celestia send Mario, Luigi, Princess Peach, and Bowser home.
The end
