Who's Got My Balls?! (D.B.奪われる!!, Doragon Booru Ubawareru!!) is the eighteenth chapter of the Dragon Ball manga. The chapter's anime adaption is the episode "The Dragon Balls are Stolen!".
Summary
Goku, Bulma, and Oolong are again driving through the mushroom forest. Oolong, curious to know why she wants the Dragon Balls, asks Bulma what her wish will be. Bulma tells him she'll wish for the world's greatest boyfriend, which Oolong doesn't think is worth the trouble. Meanwhile, Mai is watching the car from atop a mushroom, and radios to Shu to attack. Shu quickly totals the car using his Pilaf Machine, and steals the suitcase containing five of the group's Dragon Balls.
After a bit of prompting by Bulma, Goku chases after Shu on his Flying Nimbus. However, Shu has already left his Pilaf Machine, and the naive Goku believes that the empty vessel is the enemy that stole their balls. Goku returns and tells that he couldn't find the balls, but also notes that he still has the Four-Star Ball in his sack. Bulma plans to use the Dragon Radar to find the thieves' lair, but realizes that their capsules were in the suitcase as well.
Having secretly watched everything unfold, Yamcha and Puar arrive to lend a hand, still wanting the balls for themselves. Bulma is clearly attracted to Yamcha, which scares him due to his fear of women. At his castle, Emperor Pilaf is upset because there were only five balls in the suitcase rather than six. As the Dragon Ball Gang approaches the castle, Mai notes that the last ball is coming their way. After entering through the front door and following an arrow on the ground, the Gang quickly find themselves trapped when a wall pops out from behind them.
