i was in gisborne recently staying at the motor camp near the main beach for 7 days and happen to see Moko out in the surf. There were a lot of people surrounding him of which he seem to enjoy them playing with him. But I have no doubt that he could get restless and will have off days (as we have them)and maybe he wont always enjoy playing with us humans. So give him some space and excuse him if and when he does get feed up with our constant playful actions as what we enjoy we dont always get the same pleasure each day from repetition. He is a wonderful creature and should be respected and given some quiet time.
