Or..if you can draw a crocodile it could be in his mouth! Momma's idea sounds like a good one...Or..draw a large branch originating on the right that grows diagonally towards us and hides that part. This is a great pic so far VV

Your line art is awesome! If you're really having trouble with that foot you could have it resting on a branch, kinda like emma said to cover the gist of it... I'd love to see it finished.
