The level begins with Mario crossing a pair of beat block sets. After passing a couple of Prongos and Wallops, Mario finds a door leading to the inside of the level. The inside features several more beat blocks. Once Mario makes his way to the exit of this inside portion, he finds the Checkpoint of the level. There are several more beat blocks that lie past the checkpoint, found in arrangements of climbing, running, and very clever jumping.
