Lego Mindstorm NXT Scorpion

LEGO Mindstorms 8547 NXT 2.0 was first set in my adult era, which take me back to LEGO. Scorpion was not in this set models (Alligator replaced it), but it was in previous version 8527. When I spotted it , I must build it. It's sting is awesome! Something like cobra in EV3.
