Known as 52, this sea creature is unable to communicate with and befriend other whales because it speaks in a rare 52-hertz frequency that confuses and drives off ocean dwellers. According to Adrian, the whale was first detected in 1989 when the U.S. Navy picked up a strange sound emitting from a series of secret underwater microphones that had been used to track Russian submarines since the Cold War.

The fund is now well over it's goal by more than $100,000, allowed Grenier and director Josh Zeman to hire marine science experts to help them locate the lonely whale.

52 may not know it, but he or she has more Hollywood friends than most people could dream of.
