Leopold has the best songs, and they're usually the highlight of this series for me. This episode has great music all around.

In other respects: the character design is nice enough and there are a lot of gags (hearkening back to what Soyuzmultfilm's production was like in the late 1930s), but the execution is kind of sloppy (and I thought so when I watched them back then, too! There were lots of mistakes I would notice). The size of the mice varies hugely again - from being almost as big as Leopold when they're on the motorcycle, to being the size of his feet when they climb up his trousers at the end!
