The opening of a time capsule buried at the zoo a century ago forces the penguins, Julien, Maurice, Mort, Marlene and Fred into a search for the legendary cursed treasure of the Golden Squirrel, which they must find and destroy before the rats claim it for themselves, but matters are complicated when the treasure includes a curse that will drive those who seek it to fight each other until one who is ’pure of heart’ claims the treasure. This episode was originally scheduled to be aired in the U.S. on April 25, 2010, but remains unaired there. However, it aired on April 25, 2010 on the Canadian Network YTV as part of a ”Penguin Marathon”.
