Silly Mummy for not realizing...

This morning Ferguson excitedly showed me a drawing that he had done a long time ago but had then added to.
He pointed out the new characters: Batman, Spider-Man, Human Torch (bumping into fire- but liking it...) and these 2 guys. Doctor Octopus & "Wolf Man". I saw Wolf Man's hairy appendage & quizzically with an adult head asked the 5 year old what it was..
"That's his tail, of course Mummy. He's Wolf Man!!"
Ahhhhh... It's all clear now...
