Super Mario 3D Land: S8-3 (Castle)

We need 250 Star Coins to unlock this level. It's a castle. We have 30 seconds to start and Cosmic Mario's here. We get the first Star Coin over a square platform that disappears into the lava. The second Star Coin is near the second set of Thwomps. Wall jump off it to get it. Towards the end is an obstacle course with pillars. Before you jump across the gap with Podoboos, let Cosmic Mario break the pillar in the upper left corner for the third Star Coin. We run in a circle along the pillars so Cosmic Mario will destroy them so we can proceed. He disappears once we reach the clock. We get a 1-up at the flagpole.
