Buboicullaar, commonly known by Bubo, was a frog-dog in Jabba Desilijic Tiure's court who served as Jabba's bodyguard. Before becoming a member of Jabba's court, Bubo had been a spy and assassin for many years. Around 5 BBY, Bubo had arrived on the Outer Rim planet of Tatooine and joined the Hutt's court. Thought to be a simple-minded creature, Bubo was used by a Gran assassin named Ree-Yees, who had been assigned to murder Jabba. Imperial engineers had a small panel placed under Bubo's skin, which allowed Ree-Yees to track the shipments of the components for the bomb he planned to use to kill Jabba.
