Arnold was filming yet another Terminator movie, in which he was going back in time again. Some faulty wiring causes it to go haywire. He gets sent into a magical world of Equestia, where a tough, burly man like him never wants to end up. He end up in a world of bright colored ponies.

With cameo appearances and some hard to hear sentences, Arnold must figure out how to get home. As now, he is...
The Termin-Pony.
