From this point on, he tries senting numerous Waru Robots to wrecks anything around the festival and only to be thwarted again and again, all by the Wada duo.
Soon, he ran out of option as all of his Waru mecha are still under repair. Just then, he notice that Alumi is with the Wada duo and Otowa. Having noticed the failure robot is with them, he quickly turn to the other plan: Turn Alumi into his underling using the remote brainwash device that was built in her. Dr.Waruru succeeded in turning Alumi against the Wada duo, but the brainwashed robot got defeated. Having another evil plan thwarted, he had no choice but to run away yet again.
