New Super Mario Bros.: 8-5

The scenery changes from a dark world to a volcano. We're inside the volcano at the base. There's magma below. We have to platform from dangling metal platforms and rocks that will fall into the magma soon after we step on them. Jump down and quickly go up the tilting rocks for the first Star Coin. The second Star Coin is floating over the magma near two dangling metal platforms with Koopas on them. Use a shell to get the Star Coin while the metal platform is tilted. At the end, there are several tilting rocks. Move quickly and jump high to reach the third Star Coin. The pipe to the flag is just to the right.

Super Mario 3D Land: 8-5

This level takes place on ledges attached to stone walls. There are more red and blue flipping platforms. On the blue side of the last platform is the first Star Coin. We drop down some fragile stone steps to more flipping platforms. Here, several Bullet Bills fire at us, some with Tanooki Tails which give Tanooki Leaves. We reach the pole at the end and climb up. We move to another area on a yellow platform, get a Boomerang Flower, and reach the midpoint. We use a Boomerang to get the second Star Coin over a Rocky Wrench. We fell after bad jump timing.
Take 2- I got the second Star Coin, but fell trying to collect Red Coins. I'll leave them alone.
Take 3- I got the second Star Coin and made it to the other side. We go into a purple Mystery Box and find the third Star Coin in there. We wall jump to get it. Next are more flipping platforms and Banzai Bills. At the end are more flipping platforms to the flagpole, with a Rocky Wrench at the end.

New Super Mario Bros. Wii 8-5 QSC

The 2nd Star Coin is just past the midgate in between lava pillars. I threw a Bob-omb at it to get it, because the platform won't tilt far enough for you to get it. The 3rd Star Coin is near where the ravens show up. Just jump at the peak of the track and land on the platform when it switches tracks and beware the ravens.

New Super Mario Bros. Wii: 8-5 -- Tilting Platform of Doom

This level is an annoying automatic side-scroller. I was still in multiplayer mode, which made this level even more difficult. You have to ride a tilt-controlled platform over the lava. Tilting makes the platform move right and left along a track. We both made it to the midgate, but it became very difficult afterward. Periodically, lava pillars taken straight from Super Mario Galaxy will impede your progress. Luigi died in this level and got a continue, and then left. I died from the lava.

Take 2- I used a Super Shroom, which I lost to a Parachuting Bob-omb. I died on a lava pillar.

Take 3- I used another Super Shroom and lost it to a lava pillar- they don't instantly kill, like falling in the lava. I got another, but lost it to a crow and died from another crow.

Take 4- I used a Super Shroom, but lost it to a Para Bob-omb, which I used to get the 2nd Star Coin. I got the 1st Star Coin earlier before the midgate. I died in the lava.

Take 5- I used a Super Shroom and got a Fire Flower and a 100-coin 1-up. I lost my items to crows and died from one.

Take 6- I used an Ice Flower, which I lost to a lava pillar. I got a Fire Flower and lost it to a crow. I reached the end pipe and the goal.
