Ajoe met Mujoe when the heroes were running from the local authorities. Pteragodon police pursued them, but the soldiers brought out barbecue meat from the pots on their heads to distract the pursuers. When the police Charaboms finally caught up, they targeted Mujoe instead. Mujoe was disguised as Hiroshi's mother and lured Hiroshi away, but was unable to move far away from Jetters. When Jetters finally reunite Hiroshi and Mama Elephan, Jetters realized Shirobon had been carrying the unique item, a kettle capable of preserving heat for a million years, all along. Shirobon returned the item to Mama Elephan. After leaving planet Charabom, Shout told Shirobon that Hiroshi was a girl.
