DREAMZzz

Grimkeeper the Cage Monster (71455)

more
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. 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.
