On Universe 13, Ghost was training until he saw a purple 4-star Dragon Balls landed next to him.

Ghost:  Wait, is that Zaydon's Dragon Balls? What's it doing here?

    Ghost opens a portal and throws it towards the portal. On Planet Scavadania, Zaydon was cooking strawberry cheesecake and beef and rice for Queen Osha until the Dragon Balls have appeared in the kitchen and one of them hit Zaydon in the head.

Zaydon:  GAAAH!  What the--?!

    Zaydon notices the Dragon Balls and decides to put them in his bedroom.

Zaydon:  I'll use the Dragon Balls later. Right now, just getting Queen Osha better.
