A Ponicorn is part Pony, part
Unicorn. They are rare creatures that only speak in Dolphin with the occasional Monkey sound. Ponicorn's are highly sought after pets as they can grant you 2.75 wishes.
It is a well known fact that Richard Branson, Oprah and
Justin Bieber own Ponicorn's, however for obvious reasons they keep them hidden from the public.
If you ever meet a Ponicorn, repeat three portmonteaus in a row and it
will give you a gift. Gifts range from small cars, cases of Canadian domestic beer, etc...
