a short by Pixar shown at the beginning of Finding Nemo which includes a bunch of souvenirs; mainly surrounds around a snowman in a snowglobe trying to meet the Sunny Miami girl, who waves at him; his snowglobe only keeps himself from meeting her, so he tries to find a way out.

The excellent music done in the background was by Bobby McFerrin, the artist of the song "Don't Worry, Be Happy"
