Tarzan (1999)

Tarzan is a 1999 animated film produced by Disney. Based off the novel of the same name by Edgar Rice Burroughs, it focuses on Tarzan, a young man raised by apes who experiences contact with other humans for the first time in his life and he is eventually forced to decide whether to stay with his ape family or to go with the human explorers to civilization.

At the end of the film, Jane Porter jumps off a boat and the dress she's wearing inflates to a ludicrous size when she lands in the water and begins to swim to shore. Her dress deflates as she begins to rise out of the water.
