Don't Tell Mum I Made a Mammoth

Young Percy's parents are environmental activists and Percy is super OVER IT. He would rather stay home and play Xbox than go to demonstrations every weekend. Meanwhile his father wants to glue himself to a plastic bag factory and his mum has invented a machine that messes with DNA - and just might bring extinct species back to life. When the neighbour next door suddenly turns into a talking rat Percy is roped into a hilarious madcap adventure in which everyone seems to want to get their hands on the species machine - and Percy comes to appreciate what his parents are fighting for.
