Zak and Rory's Toughest Journey

Having left the Mediterranean Sea, Zak and Rory continue their adventures and travels towards New Zealand. Along the way they meet Zak’s family and a new friend, Rodger the Leatherback Turtle, and encounter a huge natural disaster. The duo and Rodger help a human sailing family fight a monster from the deep. They assist them in getting to safety on a nearby island. Having survived a natural disaster and fighting monsters from the deep, the duo leaves to fight for Zak’s life against the most skilful and the worst of monsters they encounter—humans. Zak is relentlessly chased by whalers who want to kill him. However, Rory saves the day so he and Zak can continue on to New Zealand.

Dupa ce au parasit Marea Mediterana, Zak si Rory isi continua aventurile si calatoriile spre Noua Zeelanda. Pe drum se intalnesc cu familia lui Zak si cu un nou prieten, Rodger Testoasa Leatherback, si se confrunta cu un dezastru natural urias.
