Flower 5 (38)

From where you found the flower, head to the lower-right corner and collect the Character Coin with Baby Mario.

Collect the yellow eggs scattered around if you need more ammo.

Make your way to the area below.

Go through the door into the next room.

In here, go left and switch to Baby Bowser at the Stork Stop (a type of checkpoint (an auto-save point you restart from on death)).

Head left and jump before you reach the bumpers (obstacles) to reveal a hidden winged cloud containing five stars.

Shoot a fireball at the winged cloud above the Stork Stop to make stairs appear.

Go up them and shoot another winged cloud to get five more stars.

Go up the second set of stairs and pass through the Middle Ring (a type of checkpoint).

Drop onto the egg-shooting flower.

Shoot fireballs to melt the ice to the left, allowing you to grab the last Flower.
