Twins, Adam and Evette, don't have a reputation of being well behaved children when outside the home. While staying at their grandparents' home, their grandfather tells them a story how their island home, Dragon's Lair, got its name. The story inspires the twins to search the beach caves. They discover an old chest of drawers. The whole chest drawers which act as a door, swings open to a primeval world where the twins steal three eggs: a bronze, a silver and a gold. The eggs are hidden in their cubby house where they become alive and demand the children carry out tasks. Find out what the twins have to do to avoid punishment and to receive rewards from the eggs.
