The moneky could rule. If it had actual cymbals and clanged them while shrieking as a hurryup timer (getting increasingly frantic with a chase animation on the screen) to shoot a target would be potentially hilarious if it was RARE and playing the game did not involve shrieking every 1 minute. I am not so sure what else it would be good for so limited for sure.
The claw would be fun but no idea how it would work unless you had some type of magnet to capture the ball weakly- maybe during multi ball the magnet activates and you use the crane to capture it (if other balls do not knock it loose) and then for each ball captured you get a second multiball with equal balls or a ball save or some reward. That could be pretty damn fun. Trying to manage multiball to avoid knocking loose the captive ball and also shooting for the crane switch would be great. Maybe the monkey could stary screaming if you have a captive ball and thats the hurry up to hit the crane switch.
Whatever- its an amazing theme.
