This level introduces the Spikes, an enemy that stands still throwing spiked rollers that need to be avoided. At the start head up the steps and deal with the Spikes and Galoombas. Use the ? Block to find a Super Bell , an indicator to climb the wall a little ways back to find the Stamp . Head up the ramp then into the pipe where you need to step on a bunch of Switch Panels while avoiding spiked rollers from the Spikes. Once completed, Green Star #1 appears and you can return to the outside.
Be careful as you cross the pendulum platforms with the spiked rollers, your reward is the Checkpoint Flag on the other side. Before heading up the long ramp, ground pound the circle of flowers to reveal a Super Star . Rush through the Red Ring and collect all eight Red Coins for a Super Bell as you roll through the Spikes. The large wall you ran past has Green Star #2 at the far end, you’ll need to jump from the top of the ramp and climb up the curved wall/narrow ledge of the wall to reach it though.
Ride the swaying platforms to the end, but don’t turn right. Long jump over to Green Star #3 before defeating the Spike guarding the Goal Pole.
