Round 1: Luke and Obi-Wan and Artoo and Threepio try to enter the Salty Spitoon to search for any Force sensitive sea life on the primitive backwater planet of Earth while Spongebob and Patrick try to enter the Mos Eisley Cantina to look for a source of water on the dry, desert planet of Tatooine before they dehydrate. No violence or powers just persuasion.
Round 2: All of the patrons of the MEC fight all of the patrons of the Salty Spitoon to answer the age old question "How tough are ya?". Who wins!?
