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.
