Iago and Abu are looking for a magic glass ball in Jafar's old lab because they hear that it let's you walk through walls. Once they do, they both rub it, and sure enough, they can walk through walls, but there's one catch, they are sent to the Netherworld, the land of the dead. Aladdin and the others can't hear them either, and what's really bad, is that Ayam Aghoul is trying to make them permanent guests.
