What’s in a name?

Legends abound with creatures that exist, but we never see.

There are Cyclops, Ogres, Leprechauns and Banshee.

Mermaids, Werewolves, Bigfoot and Gnomes.

The Loch Ness Monster, Goblins and colorful Unicorns.

Of this I am curious and it drives me to inquire,

Has anyone seen a Whatchamacallit or a Transylvanian Vampire?
