You’ll be using the GamePad extensively in this level, thus the name “Hands-On” it would seem. Touch the sliding screen then jump into the pipe. Defeat the Goombas and hit the ? Block at the end of the path to find a Boomerang Flower . Move the sliding doors using the GamePad and walk around to a Goomba that guards a Super Mushroom . Return then head up the steps, only to have them give out and trigger a Spike to toss spiked rollers at you. Quickly ascend and take this guy out then touch the back wall on the GamePad to reveal another Boomerang Flower before continuing left.
Jump on the P Switches before the steps then defeat the Goombas to steal their Goomba Masks , something that will help shortly. Atop the steps, hit the gong for some coins and move the sliding doors. Be patient, nothing appears at first but there’s two Galoombas guarding Green Star #1 here. Continue to the beds where you can find a valuable Green +Clock on one bed, the other has a Coin Coffer hiding in it. Grab the Super Mushroom at the end of the hall and move the sliding doors to reveal a pipe that takes you to the Checkpoint Flag . Cross over to the right side of the pit then grab a Propeller Box . Leap into the gap at the left to claim Green Star #2 then propel back up from certain doom.
Now you must collect 5 Key Coins to proceed. Key Coin #1 is behind the Thwomps on the bottom level. Up one level on the clouds is Key Coin #2 then off to the left one level higher is Key Coin #3 , it’s over the gap where the spiked rollers fall. Move right, grabbing the Boomerang Flower from the ? Block and Key Coin #4 just above; at the far right on the cloud is Key Coin #5 . It’s possible to complete the level from this screen, just use a Propeller Box to fly constantly higher using the back wall to assist, but you want to collect everything so use the Warp Box but keep a Propeller Box .
Inside you’ll find more gongs, but these ones just summon more Goombas. Some Spikes are found after the Goombas, tossing their spiked rollers but they don’t ever hit the wall which is an indicator that you can head back outside. Follow a spiked roller outside then use the Propeller Box to fly up high to Green +Clocks and the Stamp .
Go back inside then race to the end past the Spikes. Hit the gong to reveal a Mystery Box then jump inside. Defeat the Spike in this area for Green Star #3 then use the Warp Box to reach the top of the building and the Goal Pole.
