Overview
In this LEGO® DREAMZzzTM building set, kids can help Mateo and Z-Blob rescue Cooper from the Grimkeeper, who is taking him back to the Nightmare King.
Kids aged 7+ battle a fearsome nightmare figure in the LEGO® DREAMZzzTM 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.
1 set, 2 adventures
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.
Bringing the fun to life
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.
