In case you are wondering what is more terrifying than a spider big enough to step on you in the middle of the night, how about one that is also just as likely to pulverize you with its fists or punch a soda can-sized hole in your gut with its energy blaster thing. I’m talking about this imposing LEGO walking tank by Tino Poutiainen, which is appropriately named Mastadon.

The walking arsenal looks surprisingly nimble, and it can also call in some redundant reinforcements with its communication array, just to show off.
