Kids aged 7+ battle a fearsome nightmare figure in the LEGO DREAMZzz Grimkeeper the Cage Monster (71455) building set. Based on the action that takes place on the DREAMZzz TV show, the set lets kids build the villainous Grimkeeper and then help Mateo and Z-Blob rescue their friend Cooper from his evil clutches before he takes him to the Nightmare King. To rescue Cooper from the Grimkeeper, kids can choose between 2 building options. They can build Z-Blob as a mini-plane to confront the villain, or as a hoverbike to pursue and intercept the Grimkeeper and free Cooper when the moment’s right. This lets kids choose their own path and enjoy double the playtime. Minifigures of Mateo and Cooper bring the action to life. Their accessories include a belt, pencil spear and hourglass, which are important to their characters in the TV show. - Bring a villain to life – Kids can enjoy imaginative play with the LEGO DREAMZzz Grimkeeper the Cage Monster (71455) building toy set, which is based on a storyline from the TV show - Fully articulated – The Grimkeeper has a fully articulated torso, arms and legs, making it easy for kids to pose it and recreate different scenes - A torso cage – The Grimkeeper has a cage in his torso where he keeps his prisoners - Choose the adventure – Kids can choose between turning Z-Blob into a mini-plane or a hoverbike - 2 minifigures – This building toy set comes with minifigures of Mateo and Cooper - Hours of play – The set is designed for kids aged 7 and over, who will get to spend hours of fun playing on their own or with friends - Dimensions – The Grimkeeper stands over 21 cm (8.5 in.) tall - A helping hand – The set features story-led building instructions, which are also available digitally in the LEGO Builder app - Premium quality – LEGO bricks are designed to connect consistently every time - Safety is a priority – LEGO bricks have been rigorously tested to ensure they meet stringent safety requirements
