The Wampa is exclusive to set 8089, Hoth Wampa Cave. This will be the first time that the Wampa has appeared in the LEGO universe.
Minifigure Parts and Accessories
The Wampa comes disassembled in five pieces: the main body, two arms, two tusks.
The main body comprises the head, torso, and legs. The legs appear to have a 'footprint' of a 2x2 brick for connections to other pieces.
The arms have articulation at each shoulder and have hands that can hold some items and accessories, like the turkey leg he's seen with on the box. The angles of each opposing hand are twisted by 90 degrees.
The tusks attach on each side of the Wampa's face.
Army Building Potential
The expected price of this set is around $40 USD, which may dampen the ability to obtain many of these. However, I could see the desire for multiple Wampas being high. I'll rate the ABP for this figure as 'moderate' for now...
The Wampa is a cool, iconic character from The Empire Strikes Back that hasn't been seen in LEGO form to date. These two facts make the entire figure a must have.
