Hidden warp area: Locate the jumping platforms at the end of level 1-3.
Jump to the top of the screen. Near the top are three jumping
platforms in a triangular arrangement. Jump off the lower right
platform and punch the air. The sky will begin to open. Hit this
same location until a black hole appears. Jump into the hole to
enter the warp area. Slide down the steel ramp until two pipes
appear. The first pipe leads to level 5-1 and the second pipe
leads to level 4-1.
