Ride the green platform upward, then go right and drop to the green egg block below.

Replenish your egg supply.

Drop onto the yellow platform and ride it to the left.

Collect the red coin (18) and a couple other coins.

Jump back to the ledge above.

As you jump to the purple platform that moves left and right, collect the coins in the air which will give you the final two red coins (20).

From the purple platform, jump to the platform with the arrow sign on it.

Jump onto the next purple platform, then onto a green one above it.

When the green platform moves to the left, jump onto the next green platform that moves up and down.

Ride it upward, then jump onto the upper ledge and break the wooden box to get a Key.

Get back down to the horizontally-moving platform, and look upward.

Shoot the rightmost of the three winged clouds to make stairs appear.

Go up the stairs and enter the left door.

In this room, make eggs out of the enemies on the ledges.

Shoot the eggs at the piranha plants.

Kill all the plants and the final Flower will appear in the middle of the room.

Collect it.

Go through the door in the lower right area to exit.
