The mysterious creature

Once there was a creature who liked jumping from building to building. Nobody could figure out what it is, it looked like a hand but it dropped fingers so he can take whatever they drop when they run away many people thought it was going to take over the world but it couldn't cause it was just a giant hand it was harmless but very scary even police were scared of him but it didn't stop them from shooting it wouldn't die so they shot it with a stun gun and it fell but they looked at its history and saw that he helped people
