You can turn props into static creatures and vehicles. I can't remember how exactly, but the options for props give you an ability to select creations. For creatures it is more difficult, where you go into a vehicle editor, then select the Sporepedia menu again, and then entering the creature editor before clicking the green tick button to confirm your selection.
