Don't Tell Mum I Made a Mammoth

Young Percys parents are environmental activists, and Percy is super OVER IT. He would rather stay home and play Xbox, rather than going 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. And 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.
