How do you get a unicorn in monster park?

What you do, is you take a mino horn, and shove it up the roc's bunghole. Semen will begin to come out of the mino's horn and the roc will scream a scream of high pleasure. Then they will sit in the romance room for 8 more hours for no reason, and then, voila! You have a paranoid roc with a gaping bunghole, a mino with penises for horns, and not a baby unicorn. Hope this helps!
