Knick Knack is a 1989 American computer-animated short film produced by Pixar that was written and directed by John Lasseter. The short is about a snow globe snowman who wants to join the other travel souvenirs in a summer-themed party. However, the glass dome that surrounds him prevents him from doing so, thus leading to his many attempts to break out of his snow globe. Knick Knack is Pixar's fourth short and the final short produced during the company's tenure as a hardware company.
The film has been released in two versions, and each of these has been shown in both 3-D and 2-D. The original version was shown in 3D in 1989 at the SIGGRAPH program, and was released on the VHS and LaserDisc, Tiny Toy Stories, and also on the Toy Story deluxe CAV LaserDisc edition. The short was later released on May 30, 2003, in theaters with Finding Nemo. For this release, the film was re-rendered with design adjustments for the woman on the "Miami" knick-knack and the mermaid in the fishbowl. Both characters now have much smaller breasts and the mermaid is now wearing a seashell bra rather than just starfish pasties. Lasseter defended the changes by saying, "It wasn’t big bad Disney coming in and insisting we do this … it was our own choice. It was just crossing the line for me personally as a father. So I decided to reduce [these characters’] breast size."
