Day would later marry Nekroman. The two formed a band in 1996 called Horrorpops. Day is the lead singer and also plays upright bass. Day and Nekroman decided to form a band where they could experiment with many genres outside of their normal bands, and decided to start by switching instruments. Nekroman taught Day how to play an upright bass, while she taught him how to play guitar. The two began auditioning for a drummer, with Nekromantix guitarist Peter Sandorff even being a possible choice. They eventually chose Niedermeier to drum, a friend of Day's and a member of the band Strawberry Slaughterhouse, and officially started HorrorPops in 1998. After touring for a while as a trio, the band recruited Niedermeier's old bandmate, Caz the Clash, as a second guitarist.
