Saiyen Saga:
Raditz, Goku's evil brother comes and kidnapps Gohan.  Raditz tells Goku that if he kills 100 people he will give Gohan back.  Goku would not be so sinister so he finds Piccolo and They set off to find Gohan.  Ultimatly, they find Gohan with Raidtz and start to fight.  They are no match, and as Goku is being beaten into the ground Gohan breaks out of the capsule he is trapped in and launches at Raditz, he hits Raidtz and knocks him off Goku.  Goku immediatly grabs Raditz and tells Piccolo to use Special Beam Cannon.  Piccolo uses the attack and it goes through Raditz, thus going through Goku.  I'm not sure when, but sometime Raditz tells them in, one year, two stronger saiyens will come.  Goku starts his journey to King Kai's planet.  Piccolo's first training session is for Gohan to live in the wilderness all alone.  Gohan becomes friends with a dinosaur who is attacked by another dinosaur, I think.  Gohan saves his friend.  Back in the other world...  Goku falls off Snake Way.  Goku lands in the land of King Yamma.  He sees two ogres.  The one says he will get Goku out if Goku can win in a wrestling match.  Goku wins and the Ogre double crosses him.  The next Ogre comes and tells Goku if he can catch him, he will show him the way out.  Goku and the ogre get in a big race.  Goku runs awhile before catching the ogre.
After Goku catches the Ogre, he shows Goku the secret exit.  As Goku leaves he whips out the fruit he took from King Yamma's tree and the ogres try to stop him but he eats it.  Then he gets out and back on snake way.
Goku finally makes it to King Kai's.  Goku gets to King Kai's planet and finds it hard to move.  He finds Bubbles and thinks he is Kin Kai.  Goku struggles to move on this planet.  He finds King Kai, and King Kai tells Goku that his planet has 10x Eath's gravity.  Goku must catch Bubbles.  Then the training ensues.
