New Super Mario Bros.: 6-6

This can be a very tricky level. There are spin springs and Chomps attached to posts. We can ground pound the posts to free the Chomps. You might get the Star Coins out of order. The 2nd Star Coin is at the top of the level, over a Chomp's post. If you go left and down, and pound a stack of brick blocks on the way, you'll find a P-Switch. It will turn brick blocks into coins so you can reach the 1st Star Coin. Return to the top of the level and go down to the right while spinning to collect the Red Coins. Getting the 3rd Star Coin is very tricky and you may only have one shot at this per attempt at the level. Clear all of the brick blocks in the channel over the spin spring, then spring off of it. While spinning down and to the right, bounce off of a Parakoopa and hit the P-Switch above it. This will turn the brick blocks blocking the green pipe to the right into coins. While spinning and slowly descending, bounce off the red Koopa beneath the green pipe and go through the green pipe before the timer runs out. This will take you to the 3rd Star Coin. Afterwards, you'll use several cannons to make your way up. At the top will be a large set of cannons. The second cannon from the right will take you to the flag.

New Super Mario Bros. Wii: 6-6 -- Mario Star Power Make Up!

This level starts out with a slide down into an dark, underground, watery cavern. There's raft at the bottom, with a spotlight activated by switch. Tilting the Wiimote per the onscreen instructions will tilt the lamp and the beams of light will light up that part of the screen. I used a spring to get the first Star Coin. I lost the Fire Flower to a Piranha Plant, but get another and a Starman, which once again, lights up the whole cavern. I reached the midgate and got the 2nd Star Coin using the spring again. I missed the 3rd Star Coin. I lost my items to the bats Swoopers. I got an Ice Flower but lost it and died from a Fire Bro.

Take 2- I used a Super Shroom and got the 2nd Star Coin. I got the Propeller Block but lose my Super Shroom and died from the Swoopers.

Take 3- I used a Super Shroom and got an Ice Flower and the 2nd Star Coin. I got the Propeller Block and the 3rd Star Coin. I found a hidden red pipe up on the top part of the level. There's a Light Block at the beginning. I lost my items to a lot of Swoopers. I reached another red pipe at the end that took me above ground and to the secret red flag goal. This leads to the cannon, which blasts you to World 8.

Take 4- I used a Fire Flower and got a 100-coin 1-up. There was another Fire Flower in an item block, so I put it on the raft in case I needed it. I get a Starman and reach the midgate. I lose my Fire Flower to a Fire Bro, but use the Fire Flower on the raft to power up again. I reached the regular black flag goal, which takes me up to the castle.
