Cave Crusher Reviews
Brickset
Six-Wheeled Animal — “For overall design, the vehicle is very well made. The wheels give the machine some grip and width, the sawblades look cool and the launchable blade works very well. Tremorox is a great monster, and it's great to see LEGO finally selling RED Crystals.”
