Target bubble generating and target shooting systems (50, 50A, 50B, 50C) are disclosed employing a target bubble generator housing (59), a pair of left and right actuating handles (51, 55) pivotally coupled at their front ends of the left and right vertical edges of the housing (59), and a bellows assembly (116) positioned intermediate the left and right handles (51, 55) and coupled to the latter at the approximate midpoints thereof. The target bubble generating housing (59) includes a torus-shaped reservoir (81) and a vertically reciprocable bubble wand (98) having a film-forming elliptical ring structure (101) including upper and lower serrated arcuate edges (102, 104) of truncated triangular cross section to minmize disturbance of the soapy fluid in the reservoir (81) as the bubble wand (98) exits the fluid. The bellows assembly (116) generates three positive pressure airstreams during compression-one to lift the wand (98) out of the film-forming solution, one to strip the soapy film from the wand (98) to form and project target bubbles (60), and one to actuate an audible sound generator (127). During expansion, the bellows assembly (116) creates a negative pressure condition which serves to affirmatively retract the bubble wand (98). The twin actuating handles (51, 52) which are manually manipulated to compress and expand the bellows (58) serve as water ejectors capable of projecting one or two high pressure water stream (61) along parallel, convergent or divergent trajectories to enable shooting down target bubbles (60).
