Super Mario 3D Land: 7-3

We need 70 Star Coins to unlock this level, which isn't a problem, as we have 113 Star Coins. It's a nighttime level with tightropes and Super Mario 3 music. We hop up the tightropes, dodging Fuzzies, but dying from a fireball from a Fire Piranha.
Take 2- We climb up, dropping down from a high tightrope down to a lower one, collecting the first Star Coin on the way. It is to the right. We warp using the orange Mystery Box. We died trying to reach Coin Heaven using the purple blocks by a fireball.
Take 3- We fell off.
Take 4- We reach Coin Heaven. We get a Starman and run through enemies for a 1-up. The second Star Coin is at the end. We land at the midpoint and use the binoculars to find five Toads who drop a couple of Super Shrooms. We warp to more tightrope climbing. We jump up from a short tightrope for the third Star Coin. Here, the Fuzzies are moving along a white track, so be aware of where they are. We carefully climb up, avoiding enemies flying around the tightropes. We warp and hit purple blocks for a 1-up at the flagpole.

I got the 2nd Star Coin by hitting an invisible block with a vine. The block is over the leftmost blue mushroom past the midgate that is part of the large nextwork of Fuzzies and blocks. I used the Propeller Suit to get it. You can also get it by using the P-Switch. I also got a 1-up at the goal.

New Super Mario Bros. Wii: 7-3 -- Attack of the Fuzzies!

There are giant Fuzzies on line paths with blocks. I got the 1st Star Coin, but lose my powerups to Fuzzies. I powered up at the midgate. I got a Helishroom, but lose it to a Fuzzy. I got the 3rd Star Coin, lost, got, and lost a Super Shroom to Fuzzies, and reached the goal.

After reaching the goal, I won a Helishroom and a Mini Shroom at a Toad House.
