The sleeves of Coco's penguin coat are sewn together to look like flippers, so it might seem a bit awkward to wear. However, Coco's father gave the coat to her before he disappeared, so she wears it every time she goes out exploring. What Coco doesn't know is that the Goblins have a legend about a brave flightless bird and when Coco unexpectedly ends up in their realm, they all think that Coco is the Penguin who can save them from the evil Emperor of Darkness! But how can a 6-year-old girl stop an army of demons? Coco doesn't know, but together with her new friends Chaley the Goblin and Zammie the fallen Angel, she's certainly going to try in YONA YONA PENGUIN!
