Flower 5 (50)

After getting the flower, climb out and head through the dirt in the left wall.

At the first path split, head downward.

Dig into the alcove to the right and collect three coins, including a red coin (15).

Head back left and continue downward to find a morph bubble (a bubble that extends your time in your current form).

Continue going left along the lower path to find another red coin (16) in a dead end.

Make your way to the upper half of this maze.

Find another time extension morph bubble.

Below that, head down some paths to find coins; the middle coin path has another red coin (17).

Head to the far left to find a Yoshi block above some spikes.

Collect the red coin (18) at the end of that path, but do NOT hit the Yoshi block as you will die instantly.

Make your way to the lower-left area of the maze and exit through that path.

The block below you will rise upward, causing you to move around to avoid spikes above.

Collect coins on the way up, including a red coin (19) off to the right side.

At the top, head right and jump to avoid spiky enemies.

There will be a line of three coins with spikes above them and spiky enemies below. Use eggs or your tongue to clear the spiky enemies.

Hop flutter (a special jump) to collect the last red coin (20).

Go through the Middle Ring (a checkpoint (an auto-save point you restart from on death)).

Head through the door to a new area.

Outside, hop into the mine cart.

Go down the hill, then jump at the gap and into the next cart to continue the chase with Tap-Tap.

Repeat jumping at gaps and falling into the next cart to avoid the giant spiked ball.

At the end, Tap-Tap will break the flat platform, causing it to fall into the pit.

Flutter to the low ledge and pick up the final Flower.
