The first level of the game is a generic grassland level. In the beginning of the stage just like in New Super Mario Bros., Princess Peach's Castle can be seen in the background. When you start there are three ? Blocks, a few normal blocks and a Goomba. The highest ? Block will hold an item, either a Mushroom or a Propeller Mushroom. Move to the right and you will see a moving piece of ground. Move farther ahead and another moving piece of ground will be there. It has 3 Platforms above it. It has a Green Pipe in it that moves around with it. Jump in it. In the underground area there is Blocks, Coins and a P Switch. Hit the P Switch and collect the coins that were blocks. The P switch will lose its effect and you collect the remaining coins and head out the yellow pipe. If you are playing a Toad Rescue Mission a Toad should be yelling out from the ? Block behind you. Head forward and you'll find your first Checkpoint. Hit the ? Block to get a Propeller Mushroom to get the Star Coin in the air. Go past the two pieces of moving ground and hit the second ? Block for another item. Spin upwards using the Propeller Mushroom and go through the Red Ring. Collect the Red Coins and continue forward. At the end of the platform spin to the next one and then skip the next one with the Red Koopa and collect another Star Coin. Jump off the left side of the platform and find the moving piece of ground. Wait for the Green Pipe and jump in it. Wall kick up, collect the last Star Coin and head out the yellow pipe. You will be in a hidden area. Just before leaving the hidden area there is a block, hit it and collect the 1-Up Mushroom. Continue forward and complete the level.

There will be 3 pendulums. The middle & the top one will have a Dry Bones when they swinged to the right really far or the left. When you get to the top there will be 4 brown blocks.
