As Goku and Uub fight inside Dende’s lookout, an elderly Emperor Pilaf scales the outside of the lookout, and sneaks in to the inner chamber, unnoticed. He finds the Black Star Dragon Balls, and summons the dragon so he can wish to take over the world. After Goku and Uub finally ended their training and Uub leaving the lookout after bidding farewell to Goku as Goku is about to leave the lookout to return home as he tells Dende and Mr. Popo that he hasn’t been home for so long and thinks that Chi-Chi is going to be mad at him, Pilaf was about to wish to take over the world until he is interrupted by Goku as Pilaf discovers that Goku looks very familiar and Pilaf orders his assistants, Shu and Mai to fire the missiles at Goku, but Goku stops the missiles and tells the gang that they never change. Frustrated, he accidentally says that he wishes Goku were a child again so he could beat him up, unaware that the dragon is listening. The dragon grants this accidental wish, and Goku becomes a child. After Pilaf leaves, King Kai tells Goku that the only way he can return to normal is by finding the Black Star Dragon Balls, which are now scattered throughout the galaxy. However, Goku decides it will be easier to just grow up again after telling King Kai that he kinda likes being the size of a kid again, and he heads into town. There he finds Pan foiling a bank robbery while Pan is on a date as she doesn’t recognize him at first and Pan discovers that the little boy is her grandfather after Goku sees Master Roshi again and Master Roshi recognizes Goku and asks him of how did he become small as Goku tells Master Roshi that Emperor Pilaf summed Shenron and accidentally wished for Goku to become small again. He heads home for the first time in years with her, and explains to everyone what happened, which shocks Gohan, Videl and a crying Chi-Chi. King Kai interrupts their conversation. He has discovered that when a wish is made on the Black Star Dragon Balls, the planet the wish was made on will explode within one year unless the seven balls are brought back.
