[Opo, Opo! Opo, Opo!] I'm Opo the crazy dolphin, the kids think I'm I.T. When l give them all a fishy back ride, and a game of ball in the swishy tide. I'm one fish that'll never get fried, and served in batter for tea, and I live at Opononi by the sea! [Opo, Opo! Opo, Opo!] Everybody loves him at Opononi Bay. He's such fun for old and young, they all want him to stay! He's Opo the friendy dolphin, he's friendly as can be. If you should want to learn to swim, you couldn't do better than learn from him. He’ll very soon get you into trim, and he's giving instruction free, down at good old Opononi by the sea. [Opo, Opo! Opo, Opo!] Dad has to leave his golfing coz the family all agree. Sea air is good for everyone and Janet and John should get some sun. And much more fun than a hole in one is a game of ball with me. Down at good old Opononi by the sea! [Opo, Opo! Opo, Opo!] Everybody loves him at Opononi Bay. He's such fun for old and young, they all want him to stay! There never was such a dolphin in the whole of the Tasman Sea. Across the waves he likes to shoot, you never saw a fish that looked so cute. And he never wears a bathing suit not even a bee-kee-nee. And he lives at Opononi by the sea! And he lives at Opononi by the sea!
