Folklorists Iona and Peter Opie point out in The Classic Fairy Tales (1999) that the tale has a "partial analogue" in "Snow White": the lost princess enters the dwarfs' house, tastes their food, and falls asleep in one of their beds. In a manner similar to the three bears, the dwarfs cry, "Someone's been sitting in my chair!", "Someone's been eating off my plate!", and "Someone's been sleeping in my bed!" The Opies also point to similarities in a Norwegian tale about a princess who takes refuge in a cave inhabited by three Russian princes dressed in bearskins.
