The BONNETS on the clams. The mother who says not to be fooled, YET LETS HER BABIES GO with the pied piper.
Was Walt using symbolism to SHOW the world and EXPOSE the evil, or bc he was paying homage to evil? I really dont know. Im going to be honest I LOVE DISNEYLAND OK? And in my heart of hearts I want at least the original intent to be good. But I know it may be dark. Thats sad.
Anyway, this scene speaks loudly in realm of the horrors some believe to be true. SPOILER: they eat the clams.
This is what I've come to accept, too.
