Unenlagia is one of the basic Zoids Z-Builders sets. Z-Builders (known as Zoids Blox in Japan) is a modular construction system that lets you combine parts with other Z-Builders and Zoids model kits. Parts come on a sprue and have to be clipped off like any other basic model kit. The difference here is that Z-Builders uses a core set of cubes to build each creation.

Each Z-Builder comes with a cockpit with pilot and sticker sheets. However, the instructions do not give you any guide to sticker placement. You have to go by the box to figure it out. Each kit also comes with extra connector pieces to help build the Matrix Dragon.
