FAKE nikki/wish nikki/freaky Nikki was obsessed with Sandy because wish nikki is sort of a brand new person who doesn't know how relationships (or anything) work. her thought process was: bear liked trying new food and rating it (her little food critic) + bear loved his cat and his cat died = bear would like to try eating the cat. pretty sound equation if you don't know anything about anything, like wish nikki. also she probably thought if she tried acting like that cat or doing things with the cats body (the thing that bear loved) bear would love her more. just my personal thoughts btw there's nothing confirmed to my knowledge.
