This is a video of a hermit crab who's upgraded from a shell to a giant LEGO brick. Is a LEGO brick better than a shell? I doubt it. Does a hermit crab with a LEGO for a shell get laid more than one without? I doubt it. At least not unless he finds a lady crab to move in right next door! Pollution -- now that's the real issue here.
Keep going for the video, then pick up any trash you see on the way home.
