She has made a career out of doing the most impossible tasks. After she accepts a job, her abilities are such that not even the tightest security can stop her from making off with her prize (one million). Once more, she has accepted a lucrative, lofty assignment from Commander Red: steal the Dragon Balls and get rid of Goku.
To get in Dream Land, an amusement park in West City, she steals tickets from a few kids and gives it to the ticket lady. She then disguises herself as a fortune teller, and tries to get Goku to give her the Dragon Balls by telling him she knows he has two balls hidden in his clothes. However, Goku misinterpreted her reference to "two balls" and when she asks to see them, he drops his pants to reveal his testicles (this scene is edited in the censored version of the anime, and only shows Goku wearing boxers with a Dragon Ball pattern). When Hasky's followers blow their cover, Goku leaves the Dragon Balls with Yamcha and runs after her thugs. Hasky tries to tempt the shy Yamcha out of the Dragon Balls; but after the real fortune teller comes in, she attacks him with a blade. While Yamcha holds Hasky back, his girlfriend knocks him out as she thought he was making out with Hasky. Hasky takes this opportunity to tie up Yamcha and steal the Dragon Balls. Hasky reveals to Yamcha that she set up a time bomb in Dream Land and mockingly says it is too bad as she thought he was rather cute. As she is escaping in her Jet Squirrel, Goku manages to catch up with her and attach her to a wall with the Power Pole. Though Hasky resists, Goku gets the balls back by tickling her until she releases the Dragon Balls, and disarms the bomb in time.
After that, it is likely she was turned in to the proper authorities.
