Russian folk lore question: Houses that are alive and have legs, some kind of bird legs. I have seen these in some of the Russian animation/cartoons. In one of the cartoons, the house had a nest of eggs, they hatched and out came little houses, also living, with bird legs. In Летучий корабль that I posted to the cartoons thread, there is one such house with bird legs. Русские мультики на ютюбе

Do such houses have a name? Or is there a fable/story about them?
