Gaming-obsessed Max is having a very, very bad day. Firstly, he was pranked by his younger brother Liam at school, then all their devices were confiscated by their mum and to top it off the brothers and their baby sister are being babysat by the crazy lady from next door. But when Liam starts playing a game called Shrinkle on Miss McBoob’s phone, things go from bad to worse. The app shrinks the brothers to the size of minifigures! Can they beat the game before their time runs out?
