Flower 5 (49)

Make your way along the path until you reach a locked door.

Open the door to enter the next room.

Go through the Middle Ring (a type of area).

Switch to Baby Mario if you don't already have him.

Run to the right.

Break the dirt above to get the first Super Star (a temporary power-up).

Cross all the spikes while making your way to the upper tiers.

Kill ALL the Piranha Plants (enemies) in the process.

You will need to backtrack multiple times to ensure all Piranha Plants are killed, as one Super Star's power is not enough for the entire run.

Head to the right, then jump to the upper ledges and continue to the left.

You'll be backtracking a couple times to the second Super Star spawn point due to slow movement.

After you head all the way left, grab the third Super Star.

Continue upward to grab the final Flower.
