Toon Disney : Aladdin Season 1 Episode 7 : "The Vapor Chase" by keith white

Abis Mal comes across some magic powder that, when burnt, creates a smoke creature willing to steal for him. He then tricks Jasmine into buying all of the powder to give to the people of Agrabah to use as fuel. Only, after stealing from the people of Agrabah, the smoke creatures combine to form the smoke monster Sootinai, who then turns against Abis Mal and starts destroying Agrabah.
