An inflation display device comprises an inflation module including an extension portion. An end of the extension portion is connected with the main body of the inflation module. The inflatable display also includes a partition formed where the extension portion is joined with the main body of the inflatable display. Advantageously, one or more aperture(s) are defined in the partition with a circumference smaller than that of the partition. The pressure associated with the air flowing through the extension portion can be varied. By varying the pressure of the air flowing through the aperture, it is possible to animate the extension portion as the air flow travels through the tapered extension portion and exits a free end of the extension portion.
