I got all the pre-creasing done, but am having trouble collapsing. I collapsed the head fine, but am having trouble with the bottom part where the legs and tail are.
Also not sure where to go from the base since I have the head done and have no idea how to make it look like the completed module.
Also is there an easy way to tell which creases are mountains/valleys?
I just double creased them all because I didn't know which is which

Thanks all!
