Super Mario 3D Land: 7-2

We start in a room of stone with rolling spikes on chains. We die from a Chomp.
Take 2- We take a hit from a Chomp and hit the red ! block above its post. It forms stairs to the alcove with the first Star Coin. We dodge more rolling spikes to a door to the midpoint. We have to dodge rolling spikes on blue and pink platforms that tilt, making the spikes roll. On dropping platforms is the second Star Coin. We reach the end of the tilting bridge and walk up the stairs and around the corner. There are two Chomps, as well as more rolling spikes, and regular spikes. Over the spikes is the third Star Coin. We reach the stairs to the door. Behind the stairs are some coins. Beyond the door are tilting platforms to the flagpole, one of which has a rolling spike.
