The new invention by Prof. Knox is to be tested on F&F: an electronic babysitter - F&F feel too old for this. They all let their kites fly. Lupo gets into trouble when his big kite pulls him into the air. F&F can earn a few pennies by cleaning out Uncle Fax's garage, but unfortunately they also sell a vase that Fax needs - and Granny Eusebia bought it. Lucky has broken a leg; sits bored at his "window to the yard" and suddenly watches terrible things at the neighbour Old Snotty's. Little by little he sends his family over, but nobody comes back. Lucky panics.
