Take the egg box apart so you can change the end that it opens from I made holes and one end using scissors and tied it back together with string.
Cut out two eyes and two rows of teeth on some white paper. I like the effect of using a thick marker, it makes it more cartoon like. Simply stick these on and play.
Perhaps find some scenes from Peter Pan or just the ‘Never smile at a crocodile’ song.
