When you watch "Koko Sees Spooks", you need to appreciate the context for the cartoon and compare it to its competition. For the most part, the Koko cartoons of the era were simply the best made cartoons you can find. Disney didn't begin making great films until a few years later, Looney Tunes wasn't to start until 1930 and many of the competitors either weren't very good (such as the Van Buren Studios) or were good but not animated nearly as well (Felix the Cat). Here, with Koko, the Fleischer Brothers had it all...excellent animation, excellent stories and, most importantly, fun!
"Koko Sees Spooks" begins as usual...with Max Fleischer drawing Koko. But there are two things different this time. First, you don't see any more of Max (usually Koko and Max interacted a lot in their cartoons) and Koko is drawn up of many number 13s. And, apparently, this causes the story to be very spooky....filled with ghosts, skeletons and the like. Later, Koko even makes an invisible army of Kokos! It's all very surreal and cute...and the animation is excellent, even for a Koko film. The only drawback is the story itself, which is amusing but also not especially deep. Still, even if it's not among the best, it's still charming all these years later.
