This Ocean-Zoo aquarium turns into an exciting Sea-Show! A battery powered cover lights up the aquarium in COLOR and then becomes a theatrical projector. Remove the cover from the top of the tank and focus it through either side of the aquarium. Darken the room and you will see your pets swimming and dancing on a distant wall or special screen (included). The complete kit comes with Micro-View aquarium, electric projector cover, molded clear bulb cover, color filter bulb cover and Sea-Show projector screen. (batteries not included).
