Preheat oven to 350 degrees. Place butter in a 9x13 pan; place pan in the oven while the oven preheats. This will melt the butter.
Remove pan from oven once butter has melted and stir in, then pat down graham cracker crumbs, forming a bottom "crust". Sprinkle nuts over the top of the crumbs. Sprinkle the chocolate chips over the nuts. Sprinkle the coconut over the chocolate chips (see why we call them "sprinkle" bars?)
