Mark AZ Dippe and Taedong Park direct this computer-animated sequel, which continues the adventures of a brave little fish called Pi (voiced by Drake Bell) and his friends on the reef.
A year has passed since Pi defeated villainous shark Troy (Donal Logue), and the fish with the big heart has raised a family with his pink soul mate Cordelia (Busy Philipps). Alas, Troy escapes from a Navy research facility and swims back to the reef, determined to exact revenge on Pi. The shark and his posse arrive at low tide so cannot carry out their plan until the water rises. This gives Pi time to concoct a plan to recapture Troy and protect his friends and neighbours from harm. Meanwhile, Troy sends a spy, a fish called Ronny (Jamie Kennedy), to the reef to disrupt Pi’s carefully laid plans. Ronny persuades the fish to stage a talent show, which will draw human visitors to the reef and they in turn will get rid of the sharks.
