Inspired by the film 'Monster House', Barney decided to keep watch on the neighbours home. He says the lady spends far too much time cleaning her house, and it was up to him to spy on her. In 'Monster House' the boys dress up a vacuum cleaner as a person. Barney didn't have a vacuum cleaner, so he disguised his kiddie lawn mower (see photo). This lawn mower sat on our lawn all day, spying on the neighbours. There were all sorts of traps and trip wires set up across the lawn, in case someone should invade us. Lol.
