Gremlins is a good example of how cute monsters can tie into merchandising the "horror" experience. This British pressbook for the movie is chock full of product tie-ins. The merchandising page (click image to enlarge) mentions items including soft drink concentrates, backpacks, tote bags, t-shirts, jigsaw puzzles, stickers, toys, and more. Who could resist a little Gizmo doll in his little car? Of course, true horror fans prefer Stripe.
