Don't Hug Me I'm Scared - I'm scared III

Each of the three characters represents a different base human emotion.
The bird represents our inner skeptic, and the part of us that is no longer childish.
The yellow guy represents our inner child and our eyes of innocence.
And the red guy is, of course, our voice of reason.

The Red Thing strikes me as the only character who is even remotely close to sane.
