Now tramp second metal box right and follow and quickly take coin by chomp and quickly slide left again! Step up and push red sphere left for red button. Now tramp metal box down through red TP for the second stopper for the ice jump! Now tramp (through red TP) DDRD and you will end up on the conveyor tile!
