A male penguin named Peter sees a female penguin named Polly, and attempts to woo her. First he offers her an ice cream made of snow and icicle, which she accepts. He then catches her a pufferfish, but when she swallows it, she begins inflating and deflating repeatedly until Peter makes her spit out the fish, which then returns back to water.
Angry at him for being humiliated, she slaps him and leaves to swim on a piece of ice. A shark spots her and attacks her, but Peter, noticing her in trouble, rescues her before she can be eaten. The shark then chases Peter to a cliff with a boulder on top. Peter unintentionally dislodges the boulder, which falls into the shark's mouth who then swallows it. Due to the boulder's weight, it carries him to the bottom of the ocean, where fish begin making fun of him, while he begins to feel very tired and unable to escape (and possibly dying).
Meanwhile, Polly and Peter reconcile and fall in love, thus Peter's wooing succeeded.
