This Gremlins t-shirt features sketches of Stripe and Gizmo. The shirt includes the three rules for owning a mogwai: Keep Away From Light!, Don't Get Them Wet!, Do Not Feed After Midnight!!! In Gremlins, Billy Peltzer was given a mogwai that he named Gizmo. A glass of water was spilled on Gizmo, which spawned more mogwais. When those mogwais were fed after midnight, they made cocoons, which hatched the green monsters, the worst of which was Stripe.
