Mientras Momo se defiende de un ataque en las aguas termales, Okarun y Jiji entran en pánico al descubrir un cuarto misterioso. De repente, suena el timbre.
Jiji's possessed by the Evil Eye. Okarun battles him while dodging Death Worm poison attacks underground. Unable to abandon Jiji, he tells Momo to escape alone. Above ground, Momo plans to use sunlight against the Death Worm.
Momo surfaces the Mongolian Death Worm, triggering a volcano. She uses the worm as a fire hose against the lava, but the Kito family interferes. Evil Eye-possessed Jiji appears, worsening the situation.
While Seiko trains Jiji to control the Evil Eye, it loses control and attacks Momo. She manages to get through the situation, and Okarun sets out to become stronger in order to defeat the Evil Eye.
Okarun and Aira end up fighting against classical composers. Aira gradually gets the hang of it, but Okarun is unable to dodge the composers' flying musical note bomb attacks. Turbo Granny gives Okarun some advice.
The battle between Okarun and Evil Eye-fied Jiji has begun. Showing the results of his training, Okarun fights toe-to-toe against Evil Eye, going "full throttle.".
