ahh, thanks for the clarification. Since it's such a great video, I'm glad you submitted it to the sift. The more dive videos, the better!

The spaghetti monster has limbs as noodles. If you ctrl-click-and-drag between joints you can pull off limb segments. You can also Hold ctrl to add to existing limbs segments (provided there are no hands attached). If you go to the help section in the spore menu it will tell you this in the building section. You can also hold alt to copy-and-drag body parts. Hope this helps!
