The bunnicorn was a small animal found on Nepenthe, resembling a horned rabbit. It was hunted for its meat, though its body contained venom sacs that, if not removed before eating, would cause vomiting of black bile and death.
In 2399, William T. Riker made pizza containing home-grown tomatoes, Antarean basil, and "non-venomous bunnicorn sausage" for his family, Jean-Luc Picard, and Soji Asha. The bunnicorn he used had been caught earlier that day by his daughter, Kestra Troi-Riker. (PIC: "Nepenthe")
