Pet's revenge - Charles Ogden

Edgar and Ellen's creature, Pet, has always observed their antics with horror, staying out of their way as much as possible. But now he's getting his own back... Pet's secretly spiking Ellen's food with a special balm that turns her all girly - she's started sewing lace on her PJs and throwing sleepovers. Edgar is in despair. Before he knows it, Ellen has invited Mayor Knightleigh's family into their home - where they're planning to makeover the creepy building and feature it on TV. Edgar, though seriously stuck without Ellen's evil input, begins to unravel Pet's plot - but will he manage it in time?
