If you have a picture of monster, the photo is a proof that cute Leviathan and dizzy Behemoth exist in reality, even il they don't look as Chinese or mythological monsters. Good art is just lousy luck.
Street art monsters almost too tiny to be seen are not a legend, or an urban myth. Santa considered the figure too big and weirdly shaped to be human.
The devil knows a great deal, for he is old.
Don't be afraid by the small things in life (and pictures of unseen things) and use magic all the time for everything.
I do believe that Demons and Ghosts exist in this world.
