Puzzle Maker

Puzzle Maker is a unicorn mare from Ponyville.

Personality
She is cold towards Diamond Tiara and Silver Spoon and lets logic dominate her life, but is fond of other fillies like the Cutie Mark Crusaders, Apple Bloom, Sweetie Belle, Scootaloo, and Babs Seed(when she's visiting), and very friendly with the mane six and the cake twins.

History
She is enrolled in school by Cheerilee at the Ponyville Schoolhouse classroom, Cheerilee decided to take her in. She later got her cutie mark to appear when she made a puzzle piece out of old cardboard.

In Friendship is Magic
She was one of Tirek's victims just as Cheerilee was dismissing class and got her magic stolen, though it was returned when Tirek was imprisoned forever with Cerberus watching him 24/7 in Tartarus after his defeat.

Years later she has her own company. which makes puzzles since there are hospitals in Equestria for the patients to work on and as something healthy ponies can spare their free time on after a hard day's work or on weekends. Her company makes all kinds of puzzles ranging from easy 250 pieces to 2000 pieces.

Trivia
