Rajah is a tiger from the 1994 Disney film, Aladdin. He makes his first appearance in the Epic Mickey series in Epic Mickey: Power of Illusion, where, like many others, he has been sucked into Mizrabel's Castle of Illusion in Wasteland.
After his owner Jasmine has been saved she will eventually ask Mickey to find him in the quest, Tiger by the Tail.
Rajah can be found on a ledge in Castle West Hall, where an E-Ticket can normally be found. Once rescued, he will make his way to Jasmine's Room.
