Adventures with Interactive LEGO Luigi

The build itself is more satisfying than I expected for something this small. Luigi's body is constructed in layers around the internal electronics module, so you're essentially building a plastic shell and skeleton at the same time, snapping large curved and sloped pieces into place to get his rounded belly and stance right. It is not a complex build in terms of technique, but it moves fast and there is real pleasure in watching a recognizable, expressive character emerge from a flat pile of green and blue parts in under an hour.

There is nothing in here in the way of rare printed parts or new molds the way a big System set might have, the value in this box is entirely the electronics, not the plastic. That said, the moss green and denim blue color combination used across his overalls and hat pieces is distinct from anything in Mario's palette, and a few of the larger curved slopes used for his shoes and hands are shared with the wider Mario line but molded in colors specific to Luigi, so completists collecting the whole cast will want him for that alone.
