A pensive man
Angry tree without leaves
Tree is angry 'cos all its leaves have fallen
Evil tree hates leaves
Bloody tree eating fart cloud
a happy treeeeeee :)
That horrific Ticket Oak.
A rough stoney (literally) face. it's upper lip is so shrunken and inadequate that we can see the entirety of it's upper gums and teeth.
Talking guy with tounge visible
Doodle or Die is the game of "telephone" with drawing!
