How do I find Hookbill the Koopa in 4-8?
Sooner or later you will come to a door with an “X” over it. There should be Koopa Troopas to your left, a spinning arrow thing above you, and to your right there is a passage heading downward. When you first come to this important area, swallow a Koopa Troopa, and go down the passage. Spit the shell out at the Winged Cloud at the end of a narrow passage to your right. This will build a stairway to a door up and to your right. Go in that door, and you’ll find a Crate with a Key in it. Go through a door or two and you should be back where you started. This time, go up and ride the spinning arrow across the spikes, then go in the door to your right. The rest of the way to Hookbill the Koopa is easy.
