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! Jeaic is learning about ancient iron-age Gaelic warriors at school. He'd love to be able to see them for himself.

He builds a time machine to travel back in time and meet the Gaelic warriors. Let's hope it does what it's supposed to do!!
