Kim Kardashian showed on her Instagram story how serious North West is about Elf on the Shelf. This elf is popular during the holiday season, bringing joy to children as he ?reports back to Santa? every day. Yet there is one rule in the game: Do not touch the elf or his ?magic? might go away. Kardashian reported that her son Saint West touched the elf, causing her daughter to end the game. North laid the elf to rest in a bed of grass she drew with a gravestone reading ?RIP.?
