How do you copy a WHOLE creature on spore creature creator if you wanted to edit it but wanted to keep the old one?

To copy a whole creature in Spore's Creature Creator, you can use the "Save As" function. First, select the creature you want to copy, then choose the "Save" option and select "Save As" to create a duplicate. This allows you to name the new creature differently and make edits without affecting the original. Alternatively, you can also export the creature and then import it back in as a new entity for editing.
