It always irritated me when Jerry decided to mess with Tom's mind just for the pure pleasure of it. Here, Tom attempts to collect a reward on find a runaway dancing bear, and Jerry thwarts him by continuously creating music, causing the bear to grab Tom and jitterbug with him. There really is no other purpose or plot, and it's hard to know who to root for, since none of the three characters have any personality. There's really just one joke here, repeated until the ending seems obvious. But for Hanna-Barbera, the animation is surprisingly good, and it's always nice to see that Jerry has been able to find such nice mouse-sized furniture for his hole-in-the-wall apartment.
