Inflatable object with pressure sensitive pump

An inflatable object, comprising:

• a sag, configured to enclose pressurized air, and obtain a preselected shape when insufflated with air to a predetermined threshold pressure, the sag having an outer surface;
• a decorative dress, configured to cover at least a portion of the sag, the decorative dress having characteristics of a predetermined object having the preselected shape when covering the sag outer surface;
• couplings on the sag outer surface to which the decorative dress is attached;
• a frame configured to support at least a portion of the sag;
• an electric air pump coupled to the sag by a unidirectional inlet valve, the electric air pump configured to provide the insufflated air to the sag;
• a sensor, coupled to the sag and configured to detect sag air pressure;
• and
• a controller, coupled between the sensor and the pump,
• wherein the controller operates the pump to automatically maintain a predetermined threshold pressure of air within the sag as sensed by the sensor, and
• wherein the sensor and the controller are disposed on a surface of the sag.
