Piranha Plant

That mechanical mad genius JK Brickworks is back with another cool creation, and this one's from a video game classic, Mario Bros. Anyone that's played the game (and pretty much everyone else as well) is familiar with the Piranha Plant, those tube-dwelling, perpetually hungry pains in the butt. We've seen these before in LEGO, but this one's mechanical. Check out the video to see it in action and learn how it's done.

A working LEGO Piranha Plant, from Super Mario Brothers. I was inspired to build this after posting Kristal's Dragonfly model, which shares some similar motion. The model features some interesting mechanics in order to get the plant's mouth to open and close as it is raised and lowered in the pipe.
