Is Blue exorcist really based on a slush puppy? During a discussion with some friends, one of my friends said that blue exorcist is based on a slush puppy. I know some artists can get creative through a lot of things (elfen lied from a German poem) but I found this one pretty hard to believe.

 

Hence my question: Is blue exorcist really based on this slush puppy? Or on something else?
In an interview with Animenewsnetwork, he said that he was inspired by a Grimm fairy tale:

What were your chief inspirations when creating Blue Exorcist?
Kato: It originally was inspired by a Brothers Grimm fairy tale, where brothers combat monsters.  Then, I tried to make the story flip several times, and settled down into a simple structure of demons versus an exorcist.
