retractable claw ver 1.0
reason for failure: this was the first attempt at making it. although it worked rather well without any type of elastic, it didn't in fact 'retract' it just flopped back and forth with almost accurate anatomy. once the elastic intened to pull the claw back was added, it would no longer fully extend or retract. tried shortening/lengthening elastic with no effect.
problem: problem within basic idea of how to push the claw out and pull it back in.
