How do you beat the crusher on super power on poptropica?

So you go to the junkyard and you'll see Crusher. Jump on the oil cans before he knocks you off. Then jump over him and jump on to the crane. Jump quickly or you will get knocked off. Go in the crane. There will be a power magnet turn it off. Now Crusher will knock you off. Get back up and turn magnet on again. Ta-Da! One villan down!
