Art Games: Finish This Drawing

Here's the first of hopefully many art games to come. For our first challenge, it was suggested we try out a Finish This Drawing game.
I wasn't sure what would resonate with y'all, but I know I love playing with dinosaurs, monsters and beasties whenever I want to just have fun with it. Please enjoy, be creative, and I invite you to share your creations.
I can't wait to see what everyone comes up with!
