As you read this, a small group of intrepid, pink-nosed Brits are creeping through the Gambian jungle, dodging crocodiles and cobras, in the hope of spotting the legendary "ninki-nanka". This fabulously named creature is said by locals to resemble a giant reptile, up to 30 feet long and dwelling in the murk of the mangrove swamps. The "dragon" is rumoured to look rather like a game of zoological "consequences", possessing the body of a crocodile, the neck of a giraffe and the head of a horse with three horns. Less fantastically, the team's leader, Richard Freeman of the Centre for Fortean Zoology, suspects the ninki-nanka of being a species of colossal monitor lizard. "Whatever the truth," he says, "this is the first dedicated expedition to search for this animal."So far, the explorers' blog hasn't revealed any sightings. At a slaughterhouse, they were ceremonially presented with some ninki-nanka scales, which turned out to be pieces of rotted film - "certainly not biological", says Freeman. "However, we have acquired a sample to test when we get back to the UK, as it would be bad science not to investigate every claim."More encouraging are the witnesses. A compelling chap called Papa Jinda had described a scene of devastation at a pumping station where, the blog gushes, "a ninki-nanka had destroyed several pipes". It continues: "The mention of a ninki-nanka had caused a panic among the workers, and they had asked for a mirror as it was thought that the only way to get rid of the animal was to show it its reflection.
