This is a vehicle that can go on land or water. It is run around Rotorua by “Duck Tours!” and here it is coming up the wharf at Lake Okareka.
It is rather like a bus that can go on the road or at sea. I really don’t know how it works.
If you should go to Rotorua in New Zealand maybe you could try a ride with other tourists and see for yourself.
When they came back onto land, the passengers got out a device and blew into it. It sounded like, “Quack!” like a Duck. I guess these people had a lot of fun this day.
