With professionalism far from foremost concern, The Aquabats' earliest band line-ups changed with almost every concert, occasionally featuring as many as twelve to fourteen musicians at a time onstage, with the majority typically playing brass instruments. As they gradually developed a steady following and began playing shows with more regularity, the band settled into a tighter and more manageable unit consisting of around eight to nine musicians, filled out by a horn section, two guitarists and a keyboardist. It was with this type of line-up that The Aquabats began recording, independently producing the demo tapes The Revenge of the Midget Punchers in 1994 and Bat Boy in 1995.  Initially, The Aquabats intended to make each of their performances unique by wearing a different set of matching costumes for every concert, ranging from chef's uniforms to grass skirts and fezzes, all with an individual persona -- during one show wearing chef outfits, for instance, the band hosted an actual onstage barbecue. When the group's props and get-ups soon became more cumbersome to transport than their musical equipment, it was ultimately decided a singular costume was required. Terry, a future apparel designer who was employed by the wetsuit manufacturing company Aleeda at the time, acquired a large amount of spare rubber and neoprene and fashioned together a set of helmets and rashguards for the band members. The addition of customized vinyl belts, donated to the band by then-unknown artist Paul Frank, effectively completed the style The Aquabats would maintain for the rest of their career.  To accompany their distinct new uniforms, The Aquabats constructed a backstory which alleged they were actually superheroes hailing from the distant island of "Aquabania", though Larson admits the entire mythology was simply made up piece by piece as they went along from one interviewer to the next. As their mythology grew, the members soon adopted superhero stage names and identities, and began tailoring their live shows around a comic book aesthetic by incorporating onstage stunts and mock battles with costumed villains, antics which were originally ploys to get the band's friends into shows for free. Jacobs' brothers Parker and Tyler, a cartoonist and graphic artist, respectively, were brought in to help develop the band's cartoon-influenced visual style, designing their logos and promotional material as well as playing characters in The Aquabats' stage shows and mythology.  In 1995, The Aquabats independently produced and recorded their debut album, The Return of The Aquabats, pressing the CDs themselves. Having already amassed a sizable cult following for their increasingly eccentric live shows, the band managed to sell a respectable 20,000 copies of their album without any marketing or distribution. With the growing mainstream popularity of ska music, The Aquabats quickly rose to prominence within Orange County's booming ska scene, regularly touring alongside the likes of such commercially successful bands as No Doubt, Sublime and Reel Big Fish and bringing them to the brink of achieving mainstream recognition.  In early 1996, the Aquabats first drummer, Rod Arellano was forced to quit due to touring schedule conflicts and was replaced by a young 20 year-old named Travis Barker. Travis played his first show as the Baron Von Tito opening up for Fishbone at the Glass House in Pomona.
