He enjoys intellectual tv shows and stacking books. He doesn't know Spanish. He is often visited by two unicorns (a blue and pink one) who try to entice him to go on their ridiculous adventures, as much as he tries to ignore them eventually he gives into their ceaseless harassment (which usually leads into bad things such as losing his kidney).

Charlie the Unicorn lives on the rainbow and if everyone thinks you are a physco then he comes down and plays with you.
