Bosko is a construction worker, whistling happily as he uses his riveter, and making musical instruments out of everything in sight. The mice laying bricks dance as they work. Bosko uses a handsaw to decapitate a mouse and then bounce the mouse's head and its body (which is frantically trying to retrieve the head) even higher. Later, the reconnected mouse and a rivet-eating goat send a beam up to Bosko, who rides it high into the air. From this lofty position, he spots Honey in her high-rise apartment. He plucks musical notes out of the ropes of a pulley, and then uses the floating notes to step from his beam into the apartment. He puts sheet music in Honey's typewriter, and types out music as if it were a piano. Honey dances to the music, periodically disconnecting her torso from her legs. Bosko grabs the goat, which is now filled with hot air and floating like a balloon, and plays it like bagpipes. But a sudden spray of goat's milk knocks Bosko to the ground, splitting him into several selves, which play the bricks on a wall like piano keys.
