The above summary is because ccthemovieman-1 used the same summary--except he used 90 instead of 100 because his review came out in 2007.
Once again, we see in the Fleischer Brothers Koko cartoons a wonderful mix of live action and cartoon...something used very well in "Who Framed Roger Rabbit?" many decades later. Using their Rotoscope invention, Max was able to trace his brother, Dave, as he danced about and portrayed Koko...a process which made their cartoons much more fluid than their competitors and even today you have to be impressed with their work.
In "The Tantalizing Fly", a fly annoys Max as he's drawing Koko...and the fly begins to annoy Koko as well. It's all extremely funny...one of the best Koko films I've seen. However, sadly, it's also incredibly short...and is less than 4 minutes long.
