Knick Knack is a computer animated short film produced by Pixar, and directed by John Lasseter. It premiered in 1989 at SIGGRAPH, and was the last short film produced by Pixar, until the success of their full-length motion picture Toy Story (1995) and the final short made by Pixar as a hardware company. It was also the first of the company's animations to be originally produced in 3D. The accompanying score consists of a cappella vocal jazz composed and performed by Bobby McFerrin.

On a bookshelf filled with vacation souvenirs, a snow globe from Nome, Alaska sits by itself. The snowman inside (named Knick, the cousin of Frosty the Snowman, according to the audio commentary) wants to reach a "Sunny Miami" knickknack that shows a pretty girl lounging in a bikini. Knick tries several methods to break out of the globe: ramming it with the igloo backdrop, using a hammer and his carrot nose to chisel through, attacking it with a jackhammer (which causes the coals that make up his face to fall off from the vibrations), burning it with a blowtorch (which blasts him back to the far wall), and detonating explosives. None of his attempts are successful, but the blast from the explosion causes the globe to tip over the edge of the shelf and fall; he then notices an emergency exit in the base and frees himself just before he and the globe fall into a fishbowl. Here Knick sees a pretty mermaid souvenir from "Sunny Atlantis" and runs toward her, but before he can reach her, the globe settles to the bottom and traps him for the second time, possibly forever.
