BTW, Kid Vegeta. This movie could have taken place during the training period of Videl, Goten and Gohan as Goten would already have become Super Saiyan. And note, Videl never did see Shenron, but simply looked for 'Dragon Balls.' As for the Goku thing, well, Goten and Gohan did presume at the end that they had imagined it!
