Layout
This level starts with the player next to some Beep Blocks. After crossing over the small row of blocks, there is a Double Cherry. There is another row of blocks, with another Double Cherry, and more blocks to the left. After the player has crossed the third row, there are P Panels that require at least one clone to activate, causing coins to appear. Then, the Warp Box and the path to the right takes the player to to more paths that lead to the first Warp Box. After exiting the Warp Box, the player has to climb the Beep Blocks as stairs. When the player reaches the top, the Checkpoint Flag appears. After the Checkpoint Flag, the player needs to jump down the Beep Blocks before entering another Warp Box. Outside the Warp Pipe, there are some Beep Blocks the player needs to slide down. Then, the player needs to climb the final set of Beep Blocks to the Goal Pole.

Green Stars

 * Green Star 1: After crossing the fourth set of blocks, there are two separate paths along with a Boomerang Bro. The path to the left takes the player to the first Green Star.
 * Green Star 2: After the checkpoint, there is a Warp Pipe next to some + Clocks that takes the player to a bonus room where the player needs to hit the P-Switch and collect all the blue coins to receive the second Green Star.
 * Green Star 3: Once the player reaches the bottom of the Beep Block slide, there are two P Panels to press to get the third Green Star.

Stamp

 * To the left of the Checkpoint Flag is a platform that requires at least 4 entities to rise and takes the player to the Stamp. The player can also use Cat Mario. The stamp is Double Cherry.
