Getting the parts to become Gar'skuther - When you first defeat Gar'skuther, you will receive his legs. Select Replay mode, and choose the planet you were first on. Then, go to the Sporepedia, and select "Badges". Go to Park Shop. When you go down, you will see the other parts. Purchase them. You can easily afford them when you complete the game. Go to the Creature Creator. Add the body, and remove the other parts to create Gar'skuther. He may be one of the weakest and easiest to get, but he has a lot of abilities that work nicely.
