Flower 3 (49)

From the flower's corner, make your way upward along the disappearing ledges.

To the left, collect the coins in formation to find two red coins (7).

When you get to the top-right corner, make a short hop to grab the Key on the high ledge.

Head left, making short hops across the platforms to avoid hitting the spikes above.

Unlock the door and enter the room at the end.

In the next room, go through the next Middle Ring (a type of checkpoint (an auto-save point you restart from on death)) and collect the eggs as you enter the room ahead.

You will see four floor switches in here, two of which are on high ledges.

Jump to the upper ledges and shoot eggs to obtain two red coins (9) to the sides of the winged cloud.

Shoot the winged cloud to drop a Key onto the pipe, then use your tongue to grab it.

Now that you don't have a full set of eggs, Shy Guys will jump out of the pipe.

Eat them and spit them upward so that they land on three of the floor switches.

Stand on the fourth one to raise a platform below the door.

Jump onto it and unlock the door when you reach it to reach the next room.

You will enter a room which will become pitch black as soon as you walk to the right.

Head through the Middle Ring, then go right to the first red switch.

The red switches will turn on the lights for a brief moment before shutting them off again, so use them to see what's ahead before progressing.

As you wander through the dark, you will hear Boos (ghost enemies) chasing you around, so try and stay away from them.

Be sure to ground pound often to stun the piranha plants, that way you won't have to worry about their shots.

There are three red coins (12) to be recovered in this room.

From where you begin, make your way upward to a ledge where the Key is sitting.

In the lower-right area, you will find a large rubber ball next to a red switch.

Bounce all the way upward on it to grab the third Flower.
