Donny comes to the girls for protection when he's hunted by a robotic unicorn. After narrowly escaping, he reveals he accidentally released evil unicorns from a magic mirror upon Unicorn Land and needs their help to save his dimension.
Tropes:
- And Your Reward Is Clothes: Donny's mother gives Donny and the girls trucker hats in reward for their heroics.
- Chekhov's Gun: The Macaroni Trophy Donny packs when he comes to the girls. He uses it to beat the mecha-corn.
- Failed a Spot Check: The girls and Donny joke around after seemingly defeating the mecha-corn not noticing that he's putting himself back together until it gets their attention.
- Heel–Face Turn: The remainder of Stanicorn's crew join up with the good unicorns.
- Nice Job Breaking It, Hero:
- Donny was the one to release the evil unicorns in the first place by making a funny face in the darkness mirror.
- Both Donny and Bubbles flub the infiltration by getting into an argument on where the bathroom is and pulling each others' disguises off.
- One-Winged Angel: Stanicorn grows buff once he absorbs enough unicorn magic.
- Paper-Thin Disguise: The disguise Donny's mother gives the girls and her son. It's basically unicorn costumes and a mustache.
- Pass the Popcorn: During the first fight with the robotic unicorn, Donny cheers the girls on while eating popcorn.
- Potty Emergency: Bubbles has a brief one while Donny tells the Girls his story of how this all happened.
- Sealed Evil in a Can: The evil unicorns that were sealed in a mirror.
- Shout-Out: The first half is pretty much a parody of The Terminator.
- Taking the Bullet:
- Bubbles dives in the way of the blast of the Mechacorn's laser blast to save.
- The girls likewise dive to save Donny from one of Stanicorn's blasts.
- The Chosen One: As it turns out Donny was always destined to fight the evil unicorns.
