Climbing Halloween Skeletons

Step 1: Start with a cheapo blow mold skeleton ...

I bought this at one of the Halloween super stores that pop up every year, so I probably paid way more than I should have. If you wait until after Oct 31st, you can probably find these for cheap cheap!

It is a simple, 5 foot tall, blow mold skeleton, made from cheap plastic and popped together by inserting a little tab into a hole in the next bone. The problem is that the joints don't bend well, and they pop out really easy.
