Description

Building for programmers

Mindstorms combined bricks with electronics and programming, and the RCX was the heart of that early generation. Extreme Creatures sits in the part of the line that is about your own constructions: instead of a fixed model it supplies parts for building animal-like robots. At 149 pieces it is manageable and aimed at tinkerers who already have some experience with the system and want to experiment. How far the programming goes depends on which other elements you own.

Unusual colours

Black, purple, light grey and dark turquoise define the set and give it a very different look from classic Technic models. The purple and turquoise in particular are rare in this combination and make the creatures instantly recognisable. With 56 different part types there is real variety, which helps when you are working out joints, legs and housings. Colour collectors will find elements here that are hard to come by in other sets. That makes the creatures a striking eye-catcher on a shelf.

Why the parts matter

Robots need movement, so the parts have to turn, support and connect. This set brings a suitable selection, with no figures or play scenes to distract from the engineering. The appeal lies in experimenting: how does a creature walk on four legs, and how can a jaw be made to move? For Mindstorms collectors the pack is a small piece of technology history, and with used copies it is worth checking that the parts are complete. The mix of connecting and structural parts in particular gives you a lot of room when designing.

Making the most of the list

The parts list on this page shows each element with its quantity and colour, so you can check your stock and spot what is missing. Use “What can I build?” to see which other models your collection allows once these parts join it. Because Technic-style elements are so universal, they stay useful even without an RCX brick, for example in gearboxes, moving figures or frames for your own builds. That saves searching time when you are in the middle of a design.
