Billy Hart’s dad is a zookeeper. It’s the summer holidays so Billy is helping out at the zoo. Unknown to his dad and everyone else, Billy has befriended three talking zoo animals – a camel called Jaz, a baboon named Ralph and a parakeet called Carlos. Jas loves street dancing, Ralph is into money and Carlos adores TV game-shows.
Billy’s mum works in a jewellery shop. Lots of diamonds have been stolen from the shop. The police have no idea who the criminals are so Billy and his zoo mates decide to go ‘undercover’ and catch the robbers themselves! They’ll need the help of skateboards, statues and some unusual clues. Can they solve the crime or will they be uncovered and humiliated?
