Flower 4 (34)

From where you grabbed the previous flower, jump to the ledges above and go left to the pipe.

Go down the pipe and enter the door when you land.

In the room, go right and hop on the left purple platforms to turn the gear, which will roll out a ledge below.

When the gear stops turning, drop to the ledge directly below the winged cloud.

Shoot the cloud to make a red switch fall onto the platform.

Before you hit the red switch, go left and drop to the area to the left of the ledge that moved.

Head left and drop onto the thin ledges, then jump to the stakes in the lava below.

Jump to the right to grab the fourth Flower.
