This is how it works. Grandpa (your blogger) assumes the role of the "Evil Claw". Grandchildren each assume the roles of super heroes. Yesterday it was Iron Man, the Hulk, Spiderman and Wonder Woman. The EVIL CLAW usually grabs one of them and captures them in a leg lock. The rest have to attack to save their captured superhero. Evil Claw is one of my grandkids' favorite games. They each take a turn in captivity as their fellow super heroes work diligently to save them. The Evil Claw is known to tickle the captured as a form of torture.
Behind the Evil Claw you will note an knitted blanket (the cloak of invisibility) where superheroes can go to hide from the Evil Claw.
The scenario was captured on a cell phone from a non-participant. Though the Evil Claw is bigger and stronger, with teamwork and diligent wrestling, the super heroes are always able to win and aid their team members to escape.
