Welcome to the first level of Super Mario 3D Land. This isn't too hard to beat.
Before the checkpoint flag[edit]
Start by running to the right. Jump on the ledge. Hit the ? block if you want to, but all it holds is a coin. Now, either go over the white bridge or grab the coins/kill the Cheep Cheep and then go over it. It doesn't matter if you fall in the water, just jump back up. You can kill the Goomba that awaits you by jumping on its head. The ? block between the two bricks contains a Super Leaf (unless you got hurt by one of the two enemies you've encountered so far, in which case it will be a mushroom). Grab it to become Tanooki Mario (or Super Mario if you grabbed a mushroom). There is now no white bridge. Well, there is, but it's broken. Again, it's OK to fall in the water, but unless you want the Star Medal (see sidebar for Star Medal 1), run away from the camera, jump up the staircase-like blocks and jump to the other side.
If you want, you can roll/duck-spin the blocks lying on the ground. The one closer to the box has a coin, the other one has nothing. If you want a 1-up mushroom, run towards the wall and to the right. There will be an opening. Run through it and towards the camera. You will see the words 1-up appear, which means that you've grabbed it. To get out, either go back through the opening or keep running towards the camera and spin/roll into the crate that stands in your way (this is also a way in if, when over the bridge or having grabbed the first Star Medal, running towards the camera and jumping over the fence). You can now choose to either wall-jump back up or to run left, jump over the fence and on the blocks that lead you back up). If you go back to the opening, climb up the tree and jump on the blocks, run towards the camera and get another extra life. When you're back, you can get the three coins in the long ? block and use the platforms to get up. There is another Goomba awaiting you. Choose what you do with it. While you're here, check the trees (see sidebar for Star Medal 2).
Run to the left and run towards the two trees next to each other. When you climb to the top of the one to the right, a Super Leaf will appear. While you're here, it's recommended to hit the checkpoint flag.
After the checkpoint flag[edit]
Go back to where you found the Star Leaf in the tree and go through the door with the coins going in and out. You will now encounter your first Tail Goomba. Killing it awards you with a Super Leaf. In that little pit, the brick closest to the camera to the right has lots of coins in. If you spin the brick on the ledge above, you'll find a wheel. Keep spinning it to go up. Grab the coins and find the other coins in the crates. Grab the green clock to add 100 seconds to the timer. Jump off. Choose what to do with the Goombas. To the right, there's a pair of binoculars. The Toad trying to get some attention just jumps up the stairs and attempts to hit the flagpole and fails and then tries to get some more attention, although he does nothing now. Press 
, 
, 
or 
to get out of peek mode. Run up the slope.
If you don't grab the Star Medal (see sidebar for Star Medal 3), go right and jump over the gap in the bridge. The plant furthest away from the camera holds a Super Mushroom that you can get if you run through it. Walk along the next bridge. The crate furthest to the right holds a coin. Jumping on the giant Tail Goomba gives you three coins. Continue running forwards. When you see an arrow, go right. Get the coins if you wish. Jump up the blocks and jump (NOT Long-Jump) to get the top of the flag. When the map screen reappears, the game will save automatically. You can now proceed to the next level.
