Getting the parts to become Gar'skuther
When you first defeat Gar'skuther, you will receive his legs. Choose Replay mode and select 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 afford them easily 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.
Easy rare parts
To increase the chance of getting rare parts from a creature, wear the parts that you already have from that creature.
When you are a herbivore that is low on health without any nearby fruit, use a water flower on a living tree. Three fruit will grow.
Tapti: Oogie island
Defeat Gar'Skuther. Then, replay planet Tapti. There is an island that you can reach by having the water walk ability. Go to Fryse, which is the first region. Near the place where you exit into the cave to go to the next continent, look in the water on the top screen map. Notice that the water is dark blue and crossable. Go southeast until you get to an island. On this island should be a Skuther, two Oogies and a pollinated creature. These two Oogies are from the other eggs that yours was with at the beginning.
