The stone totems outside of Aunt Wu’s village
According to the official art book (p. 65), the stone totems we see outside of Aunt Wu’s village (and in the opening sequence) are based on Korean stone totems called Dol hareubang
Dol hareubangs, also called tol harubangs, hareubangs, harubangs, are large mushroom-like statues found on Jeju Island off the southern tip of Korea. They are considered to be gods offering both protection and fertility and were placed outside of gates for protection against demons travelling between realities.
