When their usual travel plans fall though, Lee Su Lin and her little brother, Su Yang, reluctantly spend their school holidays on Pulau Ubin instead. Along with their new friends, the sensible and smart Zizi, and the perpetually hungry Bus, they form the Sengkang Snoopers and discover a mysterious hut at the top of a quarry hill, where a hermit is rumoured to live. When they hear strange sounds coming from the hut, they just can't keep away, but what will they find there?
