Invitation to the Depths of Hell! Decisive Sky Battle! Start the Bungee Battle!!

Preparing to encounter the remainder of the Cyber Knights, Bo-bobo's team is seized by a warrior who fights in a rebounding bungee fight with the two most pathetic sidekicks ever: a karate-using rabbit with bad spelling and a bagface depressed man who loves cookies! But when our heroes realize all their efforts just lead to a bottomless pit, Bo-bobo covers it with a "Mystery Box" where no one knows what they'll fall into, whether it's a trap, their dreams come true...or an exorcising Jelly!
