Dragons (:
I kind of wish / hope that the awesome Viking mythology was real, all of it it to be honest. I hope when I die Valkyries take me to the eternal land where I prepare for ragnorock with all the other einherjar's engaging in daily battle, and if slain I return only to emerge back the the next day, helping my comrades and head awesome dude Odin in the mighty conquest at vígríôr hopefully sucseeding!
How about a "Werewolf". We see pics of many different ones but what would we do if they really existed ?
Uh, unicorns. Lol
Mermaids.
I was going to say the Pegasus, but then I thought about their equivalent of bird crap falling on my car. (cringe)
Dinosaurs
A talking monkey.
Mermaids
Satyr. Half man/half goat. It would just be funny watching him trying to find clothes that fit :)
