The story begins when Specter a white-haired monkey who is well-known at his home in a monkey-themed amusement park puts on an experimental Peak Point Helmet created by a Professor which increases his intelligence beyond that of a regular monkey but also twists his mind turning him evil. Imbued with this new power Specter gives Pipo Helmets to all the monkeys in the park and sets them loose having them take over the local laboratory where the Professor and his assistant Natalie (KatieNatsumi) are currently building a time machine. As Spike (Kakeru) and his best friend Jake (BuzzHiroki) arrive at the laboratory they find themselves transported by Specter along with all the other monkeys to the various reaches of time. Realizing that leaving the monkeys to their own devices could rewrite history in disastrous ways the Professor tasks Spike with finding all of the monkeys scattered across time and sending them back to the present.
