According to Daily Mail September 25: When living in the wilds of northern
Canada, miles from the nearest icy pool, what's a bear to do when he wants to
have a wash? One athletic polar bear solved his dilemma by rolling in the
snow... but he was so enthusiastic he ended up toppling head over heels. His
escapades were captured on film by photographer John Tangney who was on holiday
with wildlife enthusiasts on Hudson Bay, Canada。
