In the story, when Small Simon comes home, he tells “Big Simon” and his mother, Mrs. Carter, about his friend, Mr.
Beelzy. However, Big Simon assumed his son was in a fantasy stage. I think Beelzy, the ‘imaginary’ friend of Small Simon, is an allusion for the devil from christianity or catholicism. I don’t think the Beelzy is physically present, but he is whispering negative and bad thoughts to Small Simon. It’s a reference to Satan, because throughout the story, Simon said and did things which could be hints. As well as the title that mentions Beelzy, which is short for beelzebub meaning the devil.
