In "The Office", Dwight makes a massive profit by cornering the market on what toy?

In "The Office," Dwight makes a massive profit by cornering the market on Princess Unicorn dolls.

The scheme appears in the fifth-season episode "The Surplus." Dwight buys up the remaining stock of a popular Christmas toy, creating an artificial shortage just before the holiday. He then brings the dolls into the office and sells them to desperate buyers at a huge markup, reportedly making about $200 per doll.

The joke is a miniature lesson in speculation and supply and demand. Dwight does not create a better toy; he profits by controlling the available inventory when demand is at its peak. The gag also fits his aggressive, opportunistic personality and his habit of treating ordinary office situations like business or military operations.

Princess Unicorn is sometimes described generally as a unicorn toy, but the specific answer is Princess Unicorn dolls. The character and product are fictional creations for the sitcom, not a real toy line that Dwight exploited.
