It's seven years since Jurgen arrived at the zoo and each year he celebrates his anniversary, or 'zooniversary', by putting on a show, whether the zoo animals like it or not. This year he is planning a live music concert - the bunting is up, the fireworks are ready and Dave has been practicing his guitar riffs. But in a strange coincidence, Jurgen discovers that he shares his zooniversary with Carl the chameleon, who prefers a much quieter party to remember his arrival. Will either get the celebration they hope for?
