Caged at the back of the passage here. Bust it out.

Go through the lower of the two breakable walls to the southwest and activate the Wind Jet. Go through the second (higher) breakable wall and ride the wind to the flea at the top.

Or, if you’re a masochist, you can attempt to pogo up the spinning blades to reach the top… if you miss the lower of the two breakable walls like we did. Whoops!

Found in a cage at the top of the room. There is a block that you can push along the tracks, enabling you to make the jump over to the flea. Does not require the Faydown Cloak.
