Role in the Film
In the film, the zeppelins are used to carry Santa's bag of presents, along with Hero Boy, Hero Girl, Billy and Know-It-All, who were in the bag, to the North Pole Square. As they arrive, the Elf Lieutenant tells the other elves to begin descending, so they to stretch the mouth to let some air out as if it was a rubber balloon, but they descend too much, so some of the elves parachute off to reduce the weight. However, this does not help enough to avoid knocking the star off the tree. Fortunately, the Acrobatic Elves bungee jump off the zeppelins, catch the star before it hits the ground and put it back on top of the tree. The zeppelins then drop the bag of presents onto Santa's sleigh and the children are helped out by the elves.
In the last level of the game, while the zeppelins carry the bag to the Square, the children are taken onboard and Hero Boy is asked to take over flying the zeppelins while the Elf General helps the other elves. The player controls the zeppelins and has to avoid hitting various objects along the way, including buildings and other vehicles, in order to arrive at the Square safely and on time. When they arrive, the Elf General takes back control of the zeppelin while the children return to the bag.
