Animal possession was improved in this update with additional animals like the Crocodile. Special items were added on land as well as at sea. Lots of new sounds and characters are now in each world and their behavior is even smoother now. Achievements have an explanation section now which describes what must be done to get each achievement. Lots of other logic and alterations for a more optimized experience. (That anchoring chain took me almost 3 days to find the balance between light animation and realistic result)
