Multi colored little people

Have you ever looked into children's dreams? Such wonders live there. Take, for example, this sweet little kid over there. Yes, the one who sleeps in the arms of his father. His dreams are still what you'd call psychedelic; but did you ever wonder what creatures create those swirling, colorful patterns?

I can see them, naturally. They're tiny little things, very colorful, and they run fast. Of course, how else could they create those swirling, colorful, blah-blah-blah patterns?

They are quite wondrous, though. And very, very tasty, especially when young.
