Donut Secret 2

Start by going right of the initial block and jumping on a Koopa.

Throw the Koopa's shell at the block to reveal a line of coins controllable with the D-Pad.

Head up the ledges and grab the first Dragon Coin at the top.

Jump on the springboard to hit the block above, making a vine appear.

Position the springboard to jump onto the block and ascend the vine.

Grab the Starman from the block as it appears to the right, collecting the second Dragon Coin while moving.

Drop to the right, avoiding the hole directly below.

Ascend more ledges, collecting the third Dragon Coin.

Continue up ledges and drop down to collect the fourth Dragon Coin.

Cross the gap and more ledges to reach a diagonal slide.

Slide down and proceed across three pipes, being mindful of Piranha Plants emerging from them and the slippery landing. Being caped is helpful here.

After the pipes, go up the green pipe to exit the cave temporarily.

Hit the '?' block for a P-Balloon and use it to float to the pipe at the end. If you miss, cross the platforms and pipes manually.

Enter the pipe to return to the cave.

Go left to collect the Yoshi Coin.

Head right and hit a block for a coin.

Jump on a Koopa and use its shell to the right to defeat enemies following behind.

Go up the slope and jump on the line of Koopas to get an easy 1-Up.

Hold right, or better yet, float with the cape, to land below the next pipe and proceed to the exit. Alternatively, you can go above the pipe if landing on the ledge is difficult.
