Goal Ring (6)

Head right and jump to the platform with an arrow sign. Drop down and jump into the right side of the platform to reveal a hidden alcove containing a red coin (17).

Get back onto the platform by the sign, jump into the right wall, then jump to the upper-right ledge. Defeat the Shy Guy and shoot the winged cloud to sprout a sunflower. Hop up its leaves and go right to the outside portion.

Jump to the moving green platform, aim upward, and shoot the Shy Guy to claim a red coin (18). Flutter downward, collecting the Key that floats around. If you miss it, land on the ledge below and shoot an egg at it.

Fall to the very bottom of this room and go left into the wall. Switch to Baby Peach and shoot an egg at the Arrow Cloud, causing the egg to fall into the large red flower. It will shoot out five stars if you need them.

Hit the egg block to resupply, then go back right. Defeat the Shy Guy on the ledge, then jump to it and use your tongue to knock the spiked enemy off its perch.

Jump from that block onto the red switch, which will cause the wind to blow upward. Fly all the way up to the green platform, and jump into the right wall.

Unlock the door in that room to enter a mini-game where you gain extra lives based on how many enemies you make eggs out of within 30 seconds.

After completing the mini-game, go back left and drop down to the bottom area. Go right into another hidden opening. Knock the spiked enemy into its pit, and bounce on the ball ahead to reach the higher platform.

Collect the red coin among the regular ones (19) in the air, then go left. Hop up the ledges to reach the upper area and eat all the Shy Guys to make more eggs.

Go right and continue to the outside portion. Look above you and shoot the flying Shy Guy to collect the final red coin (20). Be quick, since it will fly away if you take too long.

Once you have the final red coin, go right and jump into the Goal Ring to complete the stage.
