Experience Hint for Teen Gohan, Vegeta and Piccolo
In Goku`s door, there is a dinosaur. Kill it and it will give you a lot of experience.

Hercule Character
To unlock Hercule (alias Mr. Satan), get to level 50 with Gohan, Trunks, Vegeta and Piccolo. Look for the gates marked "50" to collect the character trophies for each character. Piccolo's is New Namek, Trunks's is West City, Vegeta's is the Northern Mountains, and Gohan's is just outside Gingertown.

Music Hint for Vinnies Place in Northern Mountains and Three Generators
First go into the cave with the light switches and turn on the blue, green, and black ones and turn off all the other ones. Then go to Vinnies house and the silver door will be open. Inside will be one of the three generators. Break the three little orange ovals on the generator. The other generator is near the fence where Dr.Gero's (Android 20) Lab. Just go right and then the generator will be there. The last generator is on this place with a save point right next to it. You will have to take all three eggs, one at a time, down to the dinosaur on the steam vent. Don't get hit by a bad guy or the egg will break and you will have to go back and get it again and take it back down. You don't have to protect the dinosaur to do this.
