A young filly is working far from home for the first time in the city of Manehattan. She's eager to go home for Hearth's Warming to see her family... but when her career is on the line, she may have to make a tough choice.

Gadget is a child prodigy, an inventor, an earth pony, and the youngest employee to ever work at Vanderbull Industries. With boundless energy and a quartet of mechanical arms to assist her in the delicate work normally reserved for unicorns, she intends to prove herself to her mentor: minotaur industrialist Cornelius Vanderbull. However, doing so might mean spending Hearth's Warming alone, away from her family for the first time in her young life.
