Izzy & her friends have never liked school dinners & they're getting worse The dinner ladies are acting strangely (making up random rules wearing hats & cooking new food even more horrible than usual) Lollipop man mentions there is a new head dinner lady & calls her a bit of a legend (in a bad way) & that she used to be here a long long time ago & has returned Izzy & friends wonder if she is the reason for the strange behaviour They wonder why she has returned They find out she was fired They speculate as to why & decide she's a demon who's returned to do bad things Because why wouldn't she be?
