When the Sith Lord Darth Vader undertook a search for the carbonite-frozen body of the smuggler Han Solo, which had been lost by the bounty hunter Boba Fett before he could deliver it to Jabba the Hutt, Vader and the Sith assassin Ochi of Bestoon visited Bokku the Hutt. Bokku, like most Hutts, was concerned only with his own success, and was willing to backstab both Jabba and Vader in the pursuit of money and power.

Bokku should have a deep, guttural voice like Jabba, but should sound younger, stronger, and less lazy. Here is a sample of Larry Ward's portrayal of Jabba for reference: https://youtu.be/-Rv9_ZCcp9I?t=39. Bokku has 24 lines in the first two episodes of the series, paying $17.00, and will have more lines in later episodes.

NOTE: All of Bokku's dialogue is in the fictional language Huttese, and while pronunciation doesn't need to be absolutely perfect, the dialogue needs to flow like natural speech.
