How do you get the gold key from the Osmos-like area?

I'm trying to get the key from the Osmos-like (bunch of round things swimming around in a nodule) screen, and my little flying dude keeps getting knocked back. I've tried jamming the small 1-2-3 marked blobs into the holes that puff the windmill guy back to no avail. How do I get said key?

Solution 1:

You use the red cell to knock the key down you go through the one that is one hole behind the first 2 times. and the final time use the first hole.

Solution 2:

Push the red thing through three different holes until you knock the key to the ground. It's much easier to control at a smaller screen size (e.g., 60% or even 100% windowed).
