Le petit mécano

Play Safe is absolutely fantastic. The title may make the direction this cartoon is going in pretty obvious, but the anticipation makes this silly little cartoon quite enjoyable. A young boy obsessed with trains sneaks out to play with the real trains that run just a few feet from the fence around his house. When he falls off of one and is knocked unconscious, he has a dream sequence that's, as is typical is a Fleischer cartoon, gorgeously animated in pseudo-3D. Overall, Play Safe is sweet and fun, and I highly recommend it.
