The Urn of Zeus was stolen from Zeus by Ares where he kept it in a hidden cave. In order to try to impress his father, Hercules broke into the cave and stole the Urn from Ares. Later, in a scuffle with Iolaus the Urn was opened, unleashing a twister. Luckily, Hercules was able to save Iolaus from being killed in the high-winds.
