Super Mario 3D Land: S6- Airship

We need 200 Star Coins to unlock this level. It's an automatic sidescroller with the red and blue flipping platforms. The first Star Coin is on the second Airship, to the right of the green pipe. The green pipe leads to a room with Boom Boom, but you don't need to battle him. We roll through the bricks in the wall to continue. At the back is the second Star Coin over the red part of a flipping platform. There are more flipping platforms after that, with the third Star Coin over it. At the end of that is the flagpole.

Super Mario 3D Land: S6-5

This level's a Ghost House. Once we reach the edge of the floor, it breaks away and moves around, but much faster this time. Boos and red spiky plants are in the way. The floor docks and we get a Fire Flower. Lighting the torch makes a Super Shroom and two Poison Mushrooms appear. Next is a green arrow platform on a track in a foggy area. We drop down twice and find the first Star Coin at the end of the track. At the other end of the track is the midpoint. We find the second Star Coin on the spinning platform nearby, but beware the spike blocks. We hit the block in the center for a Starman and three giant Boos. I fell trying to jump off the platform.
Take 2- We get the second Starman and make the jump to a piece of floor that moves. The floor will pass Boos, giant Boos, and ghosts, then drop. We reach the door and get a 1-up at the flagpole.
Take 3- I fell.
Take 4- I made it to the door. On the wall to the right of the door are invisible blocks that form stairs to an alcove with the third Star Coin. I backflipped up the whole way. I got a 1-up at the flagpole, as well as streamers.

Super Mario 3D Land: S6-4

As if rotating blocks weren't enough, Cosmic Mario appears. He ran into me.
Take 2- I got the first Star Coin by jumping toward it and the second by running into it, but Cosmic Mario caught up and made me fall.
Take 3- I got the first two Star Coins, doubling back for the second. Near the second Star Coin is an invisible block with a Starman over the green ledge, so we get a break from Cosmic Mario. The third Star Coin is over a blue rotating block. We reach the flagpole.

Super Mario 3D Land: S6-3

This level has more of the green bridges that appear from switches. We use them to pass a Chomp. There are three item blocks over a switch. The left one has a Poison Mushroom and the middle one has a Starman. We cross some purple water and find the midpoint overhead through a gap in the back wall. Activating a bridge that goes outside leads us to the first Star Coin. The next switch takes us to some 1-ups, but I fell in the purple water.
Take 2- I fell in the purple water after getting the first Star Coin.
Take 3- I got the first Star Coin and fell.
Take 4- I got the first Star Coin and died from a bee.
Take 5- See Take 4.
Take 6- See Take 2.
Take 7- See Take 4.
Take 8- See Take 2.
Take 9- I got the first two Star Coins. I got the second Star Coin by standing on the switch below it, then jumping when a side panel appeared so I would land on a panel below the Star Coin. I did this twice- there are two panels directly below the Star Coin. I went through the green pipe and found the third Star Coin on the other side of the wall by rolling through the brick blocks. I died from the bee guarding it.
Take 10- See Take 4.
Take 11- I got the first two Star Coins and died from a Paragoomba.
Take 13- I got all three Star Coins. I backflipped for the third.

Super Mario 3D Land: S6-2

We have 30 seconds to start and land on a Goomba for 10 seconds. There are bubbles everywhere. We find the first Star Coin over several donut lifts with three Goombas. When the path forks, we go straight and wall jump for the second Star Coin. I ran out of time before I could reach the third Star Coin and a Goomba.
Take 2- I fell.
Take 3- See Take 2.
Take 4- See Take 2.
Take 5- See Take 2.
Take 6- I got the first Star Coin and got a Statue Leaf from Red Coins, then fell.
Take 7- See Take 6.
Take 8- See Take 2.
Take 9- See Take 2.
Take 10- See Take 2.
Take 11- See Take 2.
Take 12- I got all three Star Coins and warped using a orange Mystery Box to donut lifts in front of the flagpole, finishing with two seconds to spare.

Super Mario 3D Land: S6-1

It's the pyramid level, but it's nighttime now. There are five item blocks nearby: three are Propeller Blocks and two are Poison Mushrooms. We go around back and use the Propeller Block to reach a door. We go in and drop down to a lower door and go outside. We drop down some more to a musical note block and spring to a yellow platform. It raises us up partway to the first Star Coin. You need the Propeller Block to reach it. We go back inside through the same door. We bounce back up and get the second Star Coin by wall-jumping, then using the Propeller Block. We propel up to another door to the outside. We climb the stairs moving out of the wall to another door. We pass spikes on both sides and reach the door. It takes us to the flagpole. We propel from a walking Thwomp to the third Star Coin high above nearby. We get two 1-ups at the flagpole.
