Dragon Ball Manga Vol.1 Chapter 9: The Dragon Balls In Danger!!

   

 Summary

Gokū, Bulma, and Oolong are all resting and recuperating in the piggy mobile home and cooking for everyone. While Oolong marvels at Goku's voracious appetite, Bulma asks for the bathroom, annoyed by its size, leading her to decide to take a shower as an alternative. Bulma, wary of Oolong's twisted plans and request for pajamas, ends up taking a shower. During this time, Yamcha formulates a plan to lure her away from the scene to steal the capsule.
While Gokū explains to Oolong the purpose of their trip to Fry-Pan Mountain by showing the Dragon Ball piglet, Yamcha peers into the mobile home only to he was shocked and amazed to see Bulma's naked body while she was showering. Subsequently, Yamcha and Pu'ar overhear Goku working on the power of the seven dragon balls to Oolong to summon a dragon that can grant any wish. As Yamcha refocuses his efforts on the Dragon Balls to get rid of his gynophobia, Bulma emerges from the shower frustrated by the size of the pajamas Oolong gave her. After Oolong reluctantly agrees to give Bulma her clothes for the next day, he tricks her and Gokū into drinking a liquid that eventually puts them both to sleep to clear the way for Oolong to touch Bulma inappropriately.
However, when Oolong gets Bulma, he overhears Yamcha and Pu'ar sneaking into the mobile home and forces the piggy to turn into a Bulma lookalike while Pu'ar goes up the stairs transformed into a Gokū lookalike. The two changelings then leave the mobile home. As Yamcha heads upstairs and removes the covers from the bed thinking it's the location of the Dragon Balls, both Oolong and Pu'ar realize they've tricked each other outside. Pu'ar grabs Yamcha and is forced to retreat once more into cover after Yamcha is stunned to reconnect with Bulma's naked body under the sheet, not the Dragon Balls.
