Twilight Sparkle, Princess of Magic, receives a gift from Celestia.
The gift is a robotic servant to aid around her new castle. However, she soon discovers that this robot didn't come with the correct program. Her brother, Shinning Armor, was meant to receive a security drone but also didn't get the right program.
Now Spike must keep this defective machine from destroying all of Equestria while Twilight finds a solution to fix this annoying problem.

All while Tron Test meets new friends, destroys some property, and gets on the nerve of the resident princess.
