The Diergaarde Blijdorp zoo in the Netherlands is home to two very helpful hippos and one lucky duckling who happened to be in the right place at the right time after being in the wrong place and getting stuck in the hippo's pool in their enclosure.
Thanks to their help the little duck got away, although by the looks of things, he wasn't too happy with the help and booked it out of there faster than you can say Peking.
