An aesthetically pleasing decorative cover for a water cooler or water cooler reservoir bottle helps to transform the bottle from a bottle into a likeness of a person or animal without completely covering the water cooler or water cooler reservoir bottle. The decorative cover may be a three dimensional simulation of sports headgear and can include a cap to allow the user to wear the cover in a “bobble head” fashion through a cap with elastic straps. Additional features include a liner bowl for use as a chip and/or ice bowl, and may include a pivoted handle/simulated face mask.
