Awesome! Though, at the beginning I was having flashbacks of Castle on a Cloud. You are much nicer. I WANT A UNICORN TOO!

I like the last three lines, the way you have them makes the reader think about the rest of the poem.
Though I don't know if it was on purpose,but the line "It even has an alligator" makes me think that there maybe something else behind this poem.. Good. :)
