When Mr. Cooper arrives in Kauai for a vacation, Lilo, Stitch, Jumba and Pleakley convince him to stay at their makeshift hotel, "Jumba & Pleakley's Bed & Not Breakfast." When Mr. Cooper goes to inspect the hotel, he isn't too pleased about the hotel's accommodations. Later, Experiment 397 (Spats) is activated and zaps Mr. Cooper and Jumba, causing them both to fight and bicker constantly. Eventually, Mr. Cooper and Jumba's belligerence dissipates when Lilo gets everybody (including them) to count to ten through an overhead microphone. However, Mr. Cooper still complains that he never had a chance to relax, and eventually leaves Kauai. He writes a terrible review, but it doesn't matter as Penny Proud's newspaper article about aliens being on Kauai will attract customers instead.
