Comedy series starring CBBC's Barney Harwood and Nev the bear. When the sink in Barney's kitchen explodes, Caretaker Prank is called in to fix it. Meanwhile, Nev discovers the cause of the problem - a mini-fountain that Crazy Keith has rigged up under the floorboards - but he decides to keep it a secret. There is too much fun to be had watching the exploding sink turn Mr Prank into something resembling a swamp monster.
