(1) Keep your Gizmo away from bright lights, (2) don’t let him get wet, and of course (3) never feed him after midnight …no matter how much he begs. If you can stick to these rules, then you might be ready to build your very own 1980’s furball. Or it might just be safer to admire John Toulouse‘s adorable LEGO Mogwai (complete with a stylish wooden box). Yeah, that’s probably your safest bet.
