Pegasus doesn't have a horn sticking out of his head. They must be winged unicorns and not horned Pegasuseseses ses.
Yep. Winged unicorns. No such thing as a horned Pegasus*, and Pegasus was one of a kind, and didn't have a horn.
Anything else must be a unicorn, a winged horse, or a flying unicorn.
*not that there's any such thing as a unicorn or a winged horse either; I know that.
