Le Secret du docteur Flatt

The village is safe again but Snow's parents wonder where the dragonball was. Eighter had it all along so General White wouldn't exterminate the village. Unfortunately Eighter cannot risk staying in the village with the bomb still inside him. The chief suggests they go to Dr. Flappe to sort the problem. Goku has broken his dragon radar. While Snow, Goku and Eighter head to Dr. Flappe, Murasaki (who has survived) stalks them. Before Dr. Flappe can get to work, Murasaki surprises him. It is revealed Dr. Flappe created Eighter, not the RR Army. Murasaki forces Dr. Flappe to swipe Goku's dragonballs. Goku chases and beats the ninja. Dr. Flappe is able to take the bomb out of Eighter but cannot fix Goku's radar. Goku throws the bomb which kills Murasaki.
