There's a long tradition of horror stories set in Antarctica. H. P. Lovecraft set In the Mountains of Madness in the white continent, featuring a race of giant cave-dwelling albino penguins who shrieked “Tekelili!” over and over.
Happy Feet Two continues the tradition of Antarctic penguins repetitively crying out horrific noises. Instead of shout-outs to Edgar Allan Poe, however, these penguins cry out dated pop songs. The horror, the horror.
