It isn't, but that doesn't really matter. At 12 months, babies don't really get scared because of "spooky" things; they are very basic in what scares them at that age -- mostly being separated from parents. Really loud noises will startle them, and being jumped on by large animals, but that's about it. They just don't know that spooky/macabre means that you are supposed to be scared. Age 2 is a different story, and it really kicks in at 3, when they start to get scared of the dark and scared of the unknown. With DS WDW at age 3 was almost a waste -- he didn't want to ride ANYTHING that he had previously enjoyed many times.
DD loved Wishes last year, but we just took her to a fireworks show last week and now she is frightened of the concussions. She's 25 months old.
