This is a "Brickoid", a LEGO-style gyroid akin to Lloid and friends in Animal Crossing games. The design is a little repetitive admittedly (each layer is a series of very similar elements), but the layers use a few different types of techniques, including off-angle hinges, radial design, etc. The arms would twirl in unison to mimic the "gyroid" effect seen in some of the variants in the games (red circular arrow). There are two Easter egg style mini-brickoids inside. Only the upper one is easily visible by lifting the top off (small number of anchors akin to modular design, red vertical arrow), the second is buried in the center of the body (a completely unnecessary but Easter-egg type idea).
Added two images as examples of colour plates or DOTS type decoration.
