Bill Fagerbakke voiced SpongeBob's best friend, a starfish named Patrick Star, in the episode. He auditioned for the role after Kenny had been cast as SpongeBob. Fagerbakke said, "Steve is such a lovely guy, and I had absolutely no feeling for the material whatsoever." He described his experience in the audition, saying, "I was just going in for another audition, and I had no idea what was in store there in terms of the remarkable visual wit and really the kind of endearing child-like humanity in the show. I couldn't pick that up from the audition material at all. I was just kind of perfunctorily trying to give the guy what he wanted." For the part of Squidward, Hillenburg originally had Mr. Lawrence in mind for the role. Lawrence worked with Hillenburg and Drymon before on Rocko's Modern Life, so while working on the episode, Hillenburg invited him to audition for all the characters. Drymon said, "We were showing Doug the storyboard, and he started reading back to us in his Tony the Tiger/Gregory Peck voice. It was really funny, and we wound up having SpongeBob use a deep voice when he entered the Krusty Krab for the first time." Hillenburg decided to give Lawrence the part of the series villain, Plankton, instead. Music The episode features the song called "Livin' in the Sunlight, Lovin' in the Moonlight" by Tiny Tim. At the point the pilot had already been completed, music editor Nick Carr was asked to retool the existing music on it. Carr said "When I first started on SpongeBob, my duties were mainly music editorial but would quickly thrust me into the composers/supervisor chair." The production team placed most of its music budget on using "Livin' in the Sunlight, Lovin' in the Moonlight", which Carr described as "a sadly familiar scenario with most cartoons for television. By the time it comes to consider the music, the budget is blown." The idea of using "Livin' in the Sunlight, Lovin' in the Moonlight" originated when someone sent Hillenburg a tape with "a bunch of music." While the writers were developing the show outside Nickelodeon, Hillenburg played the song for Drymon as an example of the enthusiasm he was looking for. When it came time to write the pilot, they had the idea to use the song in the third act. The crew eventually got the rights to use the song
