New parents Pi and Cordelia have been enjoying a period of quiet since their last run-in with the reef's resident shark Troy.

Seeing an opportunity to kidnap Cordelia, Troy sends his loyal factotum Ronny into the community to distract Pi and the rest of his friends and neighbours while he concocts his plan of revenge.

But with Pi weary of strangers coming to the reef, it isn't long before he recognises Ronny's real intent and so sets about stopping Troy once and for all...

Animated road trip adventure. Kate (voiced by Hayden Panettiere) and Humphrey (Justin Long) are two young wolves from a National Park in Canada who find themselves shipped halfway across the country by the park's rangers. While Humphrey is a streetwise, fun-loving Omega wolf, Kate is a sleek and sophisticated Alpha wolf and considers herself Humphrey's superior. Thrown together in a foreign land, and faced with a journey of over a thousand miles to get back home and restore peace on their warring home turf, the two must overcome their differences and learn to look out for each other.
