Abstract: The present invention is a nozzle gun assembly that is axially mounted toward the front of the water gun barrel of a conventional pump-action-type water gun. The nozzle assembly has a nozzle head with a control wheel section. The squirting of the water gun simultaneously causes the actuating member to act against the control wheel, thereby turning the nozzle head on its axis. In this manner, as water is pumped through the nozzle head and out the nozzle, the nozzle head is accordingly rotated so that the stream emitted from the water gun travels an angular path, eg. from left to right. The assembly also has means for disconnecting the actuating member from the control wheel so that the water gun can be utilized in a more conventional manner.
