Kill the Cacatac with a Power Bomb or Bombs, then jump over the projectiles it has spawned. Without a way to kill the Cacatac jump over it and land on one of the last pixels of the corner without touching it. From the left edge where the Cacatac was, pause then press left and jump just before the pause fully triggers. Disable Spring Ball in order to get a large horizontal boost. Pause again as soon as possible and re-enable Spring to reset fall speed.

With the Cacatac alive, Samus can only use the last 4 pixels of the ledge; with the projectiles alone, she has 10 pixels available.
