When Mr Hammond asks Andy to open the new brilliant bugs exhibit at the park, Andy couldn't be more delighted. But when Mr Hammond asks Andy a question about how the darkling beetle of the Namib desert drinks water, Andy is flummoxed. If the grand opening is to be a success, Andy needs to know the answer! Jetting off in his safari mobile, Andy heads to the Namib desert in Africa, in search of a darkling beetle that will hopefully show him how it drinks. Along the way, he shrinks down and meets a Namaqua chameleon, but gets quite a shock when he realises it's trying to eat not only the darkling beetles, but Andy himself! Making his escape, Andy follows the beetles up a giant sand dune where he's surprised to find it's particularly foggy. Here, he witnesses first hand just how the beetles drink. But will Andy make it back to the park in time with the answer and before the exhibition opens?
