Birdman or Birdbrain?

When The Book pages transform into rongorongo script, Freddi, Samantha and Fred transport back to 1765 to Rapa Nui (a.k.a Easter Island) and end up facing a 15-ton Moai! It's just another day at the beach as the Trio jumps off cliffs, swims through shark infested waters to the Birdman's Island (Motu Nui), oh and tries to find The Book along the way!
