Gizmo can’t get wet, which means that creature has literally never gotten a bath in his entire life. Just imagine how bad he smells. Forget the Gremlins; Gizmo’s B.O. really scares me. 

(Also: I spent a large portion of my elementary school career trying to recreate a working version of Gizmo’s paper clip bow and arrow with little success. I can’t possibly be the only one.)
