Jafar's Lamp

Jafar's Lamp was the prison of Jafar and Iago.

Aladdin
At the end of the film Aladdin, the title character tricked Jafar into wishing he was an all powerful genie. Aladdin knowing he will be sealed into a lamp for eternity to do a master's bidding, holds Jafar's black would-be prison that appears once the wish is granted by Genieand it sucks Jafar (while pullingIago) inside. Genie then sent the lamp far into The Cave of Wonders for 10,000 years.

The Return of Jafar
In The Return of Jafar, Iago managed to escape the lamp, but instead of releasing Jafar from it, he threw it down a nearby well, due to Iago having grown irritated that Jafar doesn't grant him credit when it is due, and instead used him (with Jafar also making the grave mistake of reminding Iago shouting "Polly Want a Cracker" at a Bazaar that finalized Iago's decision). Abis Mal then found the lamp at the well and rubbed it, releasing Jafar. At the end of the film, Aladdin and his friends tried to capture Jafar's lamp so they could destroy it, which would thus destroy Jafar. In the end, a wounded Iago, having fully turned against Jafar, kicked the lamp into a lava pit and it melted away, causing Jafar to implode into a cloud of dust, killing him.

Trivia
