A school has had to call off its swimming gala after two beluga whales were found using its indoor pool!
The pair were found on Saturday morning at St Jonah's school, Leeds, as staff got the pool ready.
Headteacher Bill Igfish said: "All the kids were disappointed when we called the competition off - but they soon cheered up when they saw the whales!"
Police don't know where the two whales, who pupils have called Flim and Flam, came from, or how they got in the pool.
Chief Constable Herman Melville said: "We're at a loss as to how the huge creatures were carried through the school grounds, miles from the sea or any aquarium."
Pupil Nick O'Treal said: "I trained for ages for my race, but I'm not upset - I've made two new finned friends!"
Flim and Flam are in good shape, and will be taken to Scarborough's Ocean Centre in a few days.
