The Mutant Force members seen there are Lifter, Peeper, Shocker, and Slither. He takes the name "Peeper" and joins Slither, Shocker, Lifter and Burner. He also owned the winning racehorses Hero, Juniper, Single Peeper, Yorick, Traveller and Nonpareil. Hyams made "Peeper" (1975), for the producers of "Busting" with Michael Caine and Natalie Wood. Peter Hyams' career was in a slump after the failure of "Peeper" (1975). The spring peeper has no special status in most areas. Peeper, the usual leader, was absent for their first mission with the Secret Empire. The spring peeper can live an estimated three years in the wild. Peeper and Mutant Force were later employed by Professor Power's Secret Empire. "The Peeper" was made into a flash cartoon, which is readily available on the Internet. At the forefront of this new wave of audio-only comedic groups is "Peeper Radio Theatre". Peeper now called himself "Occult" and wore a helmet to hide his features.
