Thank u!!! Done it now!!!

Does anyone know how to get key by the steel boxes and kill kaboom and chompers? Have got stinky etc to get all the bonuses but now get stuck?

Cheers, done it now! Now I'm stuck on 'Loof is lost'. Got loof to the red button and got the other 3 thru and got all bonuses. Do you know how to move steel boxes and kill kaboom to get key and how do kill the chompers??

I've figure out how to get steel boxes away from red teleporter but somehow need to get steel box onto conveyor button on the left. Can't do this without getting killed by boulder or it just goes round and round the conveyor belt!! Please can someone help??
