From JK Brickworks:

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. In this video I explain how it all works.
