Alex Neptune

For as long as Alex Neptune can remember, the ocean has been trying to kill him. So he's not too happy when a bunch of sea creatures drag him to the abandoned aquarium on the hill, where an imprisoned water dragon needs his help. But how can he say no to a magical creature? Recruiting his tech-genius best friend Zoe, legend-lover Anil, a sharp-shooting octopus, three acrobatic otters and a thieving seagull, Alex plots a heist to break the dragon out. And suddenly discovers the power of the ocean at his fingertips...

Alex Neptune is struggling to get to grips with his new oceanic powers...so the last thing he needs is Haven Bay being attacked by pirates in a ship made of rubbish. The marauders are hunting for the missing egg of the elusive water dragon—and Alex is determined to reach it first to stop them stealing its power. Along with friends Zoey and Anil—plus a clumsy seal, a lock-picking hermit crab and some seriously menacing otters—Alex sets out on a treasure hunt to a secret shipwreck where they must face three monstrous challenges.

The sea creatures near Haven Bay are acting very strangely, attacking boats, and Alex senses some dark power is controlling them. When he tracks down his friend the water dragon, he finds it's been infected too. If he can't find a way to stop it, the deadly parasite it's carrying could spread throughout the seas.
