Rotta

Rotta, a.k.a. Jabba the Runt, a.k.a. Jim Henson's Slimer Babies, was Jabba Desilijic Tiure's completely legitimate, not at all bastard child. He was an ugly little spud. A living booger. He lived inside Jabba's brood pouch for his early existence, and then started sneaking out at night. He got his milk by sucking at Jabba's hermaphroditty man-titties.

Ziro the Hutt conspired with Dooku and Asajj Ventress to have Rotta kidnapped, leading to an extremely silly adventure involving Ahsoka Tano carrying him around in a backpack. Ugh. It's as entertaining as it sounds.

Jabba wrote his ugly, worthless son out of his will. Maybe he died. Nobody knows or cares.
