In the forest it never crosses the log because there were hungry predators like birds and emus but the lizard cross the log it was not scared of anything. But then a eagle came flying down right towards the lizard it had no where to go but then a creature came as fast as a plane the lizard had no idea what it was it tried to follow it but could not catch up to it
