To get a load of creature parts, fight a certain monster until you get a part from it. Example: I killed supupies until i got their body,arms,legs,mouth,ext. also you can see if you need any more parts from a specie of spore by going to the sporepedia and tapping the creature with your stylus. look to the far right of the top screen:the parts you have of that species of spore is checked off and highlighted in blue.I hope i helped! P.S. supupies are WEAK!
