Yeah, generally food like that is Spooky Food. That, along with Gross food is generally just kinda considered "food that you probably shouldn't actually eat" for the most part. So yeah, in general, I presume that most Neopians don't actually eat that kind of thing, even though they technically can. But things like that are generally sold in the scary regions like Haunted Woods; potentially one of those things that can happen to Neopians if they fall to the wrong kind of crowd~
