penicorn 

A unicorn with a penis on its forehead instead of a horn. It can prod and poke with the same effectiveness as the unicorn. Ovbious to which gender this creature happens to be.

The penicorn frolicked gaily among the flowers...unbeknowest that poachers come in search of the rare sack it carried proudly on its forehead.

Pegacorn 

A combination of a Pegasus and Unicorn, strong enough to beat sasquatch.

Sasquatch is way stronger than both a unicorn or a pegasus, but a pegacorn could totally take him.
