Jeaic has a pet dog. called Lúlú. Lúlú is always trying to get into the house, and Mamaí is always shooing him out again. If that isn’t bad enough, Jeaic is a bit of a scientist. He loves mixing chemicals and inventing machines. Poor Mamaí has her work cut out for her! The Gardaí say there’s a thief at work in the area. Daidí and Mamaí want to get rid of Lúlú, and buy a guard-dog instead. But Jeaic has a better plan. He is going to build a robot that will catch the thief. But Mamaí and Daidí aren’t too sure about that!
