There are directions on how to make a horseshoe crab paper puppet at the Baltimore Aquarium's website. I used these directions to make a horseshoe crab paper puppet. Above is a picture of me and my puppet.
The picture on the left shows the front of the horseshoe crab. The picture on the right shows the back on the horseshoe crab. If you like to make puppets, you should try to make one of these puppets.
