From the Super Mario Wiki, the Mario encyclopedia
The level begins with a Conveyor Belt, where Mario must jump across a wide field, stomping on Goombas and bouncing on Bumpers. Afterjumping off of a Swinging Claw, Mario must maneuver around Grinders using Swinging Claws to hit an ON/OFF Switch and reach the Checkpoint Flag. Mario must then spin jump on a parachuting Big Thwomp to leap over a Spike Trap, and then go under some Monty Moles later on. After passing a 30-Coin, Mario must continue spin jumping on the Big Thwomp to carefully avoid some Bumpers, then two Fire Bars, then an angry Big Wiggler, where he is then led to a 50-Coin and the Goal Pole.
