The Ohayashi Aliens are a pair of puppet-like robots featuring zippers that open and close their mouths, designed around traditional Japanese "ohayashi" festival music. They first appeared in the 15th episode of *Otasukeman*, part of the *Time Bokan* franchise. Summoned by Sekovitchi before Ojamaman's battles, they perform a specific song intended as ironic encouragement. Its lyrics translate to: "Dare to do it, dare to do it, dare to do it! I think it’s kinda useless but dare to do it, zip!" This performance serves to mock Ojamaman. During the series, selected viewers provided the voices for the Ohayashi Aliens. This participatory element continued in the *Time Bokan: Royal Revival* OVA, where musician Hiroto Komoto and manga artist Kahiro Okuya, both Sekovitchi enthusiasts, voiced the characters.
