Alternate Character Interpretation: All of the "monsters" that appear are subject to this. The story can seem entirely different depending on whether you believe a character is supernatural or just quirky.
Are the kids really encountering supernatural monsters or are they just a bunch of paranoid sociopaths who enjoy tormenting people?
On ocassion, if they are monsters, the supernatural creatures come off as just guys trying to cause as little trouble as possible. The plot of "Leprachauns Don't Play Basketball" has the kids save Ms. Jeepers from a vengeful leprachaun. She even shows a little appreciation for it.
