The Magic Broom is the key subject of the episode 31. Swept Away.

At first glance, this is a common broom, but it turned out that it is magical — it can fly. Masha first liked it very much, and then the Bear read to her that if this broom continued to be used, then Masha would turn into Baba Yaga. But Masha was lucky — the broom found its flock and flew south.
