Fortunately for Pilaf and co., their spy robo catches the locations of the approaching DB trio (closely followed by Yamcha and Puar), and Shuu and Mai leave quickly to steal their dragon balls. Shuu (in a handy mecha suit) blows up their car, and quickly snatches their dragon balls away.
"He's dead... what a weakling." says Goku with obvious disappointment.
Goku reports that the dragon balls have been taken away, and Bulma wails in lamentation that she won't get her wish... until Goku reminds her that he still has his Grandpa's 4-star-ball. But with no car, they have no way of traveling to Pilaf's castle... until Yamcha and Puar decide to assist again (so that Yamcha can get the dragon balls for his own, shyness reducing usage).
Admittedly, the boy needs help.
Back at Castle Pilaf, Pilaf celebrates his victory... until Shuu and Mai point out that a dragon ball is still missing. Pilaf responds in a fury - and tells Shuu and Mai they won't get any dinner.
But lucky for them, the dragon ball is on its way. Goku, Bulma, Oolong, Yamcha, and Puar enter Pilaf's castle with slight trepidation... exactly what sort of traps will the mysterious dragon ball thief have in store for them? Well, apparently, some Scooby Doo haunted house shit. Pilaf controls a defense mechanism, in which pillars fly out of the walls and attempt to crush the DB Crew. But pillars are nothing Son Goku can't handle.
Pilaf openly complains about the pillars, wanting to know who designed them. When Mai tells him that he did, he promptly shuts up.
And then, he captures the DB Crew with one simple tactic.
Arrows on the ground, designed to led the unsuspecting Pilaf enemy into a trap room.
And it succeeds remarkably.
"Well... there's an idea."
"I can't believe they fell for such an idiotic trap..."
