Gather round and witness the tale of the last voyage of the Maple Leaf, with the dread pirate Cap'n Tractor at the helm. A shipment of hay is under threat, but Applejack doesn't believe pirates even still exist - and Rarity has been reading far too many trashy pirate romances.
Everypony is in for a bit of a surprise.
I've had the bloody song stuck in my head for an entire day, okay? Don't judge me. The idea of AJ and Rarity being victims of agricultural piracy just struck me as inherently funny, and I had to get the idea out of my head.
Very definitely inspired by IMMATOONLINK's hilarious Canadian Horse Pirates, itself a video accompaniment to Captain Tractor's cover of the amazing song "The Last Saskatchewan Pirate", originally by the Arrogant Worms.
