Evil Jar

The Evil Jar is a magical device used by Ganon in the animated series. Located in the Underworld, it keeps all of Ganon's minions within, and he is capable of summoning them from the jar any time they are needed. Any time Link zaps Ganon or one of his monsters with the Crissword, they are magically transported back to the Evil Jar, thus keeping them from disappearing forever.

Although other Hylians are not usually capable of being zapped into the Evil Jar, in "The Missing Link" episode, Ganon creates a Wand of Power that shoots a powerful spell to captures its victim within the jar. Although the evil wizard tries to capture Princess Zelda, the spell ends up engulfing Link instead, whose body gets taken inside the Evil Jar while his spirit remains in the overworld. Eventually, Link is reunited with his body and is able to escape from inside the jar by using a bomb, causing the Evil Jar to explode and flood the Underworld with the water that was within it.

Despite ostensibly being a prison for his minions, Ganon's underlings are able to break out of it quite easily, as shown in the episode "The Moblins Are Revolting," where the monsters push out the eagle statue that covers the top of the jar and allowing all of Ganon's minions to escape.
