The Talking Fetal Horse is an unborn horse fetus, who appeared in "Makeover Makeover Makeover: the Makeover Episode".
In "Makeover Makeover Makeover: the Makeover Episode", Nostradamus made a promposal to Helen of Troy, by stuffing himself inside of a real horse. The horse walked up to her and Nostradamus tore through the horse's belly, killing her and taking out an unborn fetus. The fetus then screeched "Helen of Troy, will you go to the prom with Nostradamus?" Disgusted, Helen rejected him and Nostradamus dropped the fetus in anger and told her that he knew she was going to say that. Cleopatra later stated that promposals involving talking fetal horses were becoming a cliche.
