I play Minecraft Dungeons and I made it myself. Clam is from Minecraft dungeons a clam throws a player up.

Steps to make-

1. Cut and fold and paste all the part of the clam(Not the joints)
2. First cut a paper and paste it in between of the clam's joint.
3. then paste the cylinder on the pasted small piece of paper.
4. If you want then you can stick the block joint part on the cylinder in the manner I have done.
5. Enjoy and if have any question then comment.
