LEGO Mixels 41504 Seismo Building Set
The industrious Cragsters are a tribe of miners who have made their home in a network of tunnels and caverns dug deep under the surface of the world. SEISMO is a quiet and shy Cragster and just a nervous tap of this Mixel's huge feet can cause an earthquake. This can be useful when Nixels attack because SEISMO's stomp can cause an avalanche to bury them.
