What is the answer for the question: Who does Peter save from the shark? from the following article ?  On an island near Antarctica, a male penguin named Peter sees a female named Polly, and attempts to woo her. First he offers her an ice cream made of snow and icicle, which she accepts. Next, he tries catching her a fish, but only succeeds in catching a pufferfish. Polly accepts it graciously, but when she swallows it, she begins inflating and deflating repeatedly until Peter makes her spit out the fish, which then returns to water. Peter shrugs in embarrassment, but, feeling humiliated, Polly slaps him and leaves to swim on a small iceberg. On the shore, Peter kicks himself for letting her get away, but then notices a sharkfin moving towards Polly's iceberg. He squawks a danger warning to her, but Polly ignores him, thinking that he's just begging for forgiveness that he won't get. Soon enough, the shark attacks Polly, who swims away in panic. Needing to act, Peter picks up a stick and charges out to help.  The shark chases Polly around the bay for several minutes. When it looks like he has her cornered, Peter arrives and clobbers him on the nose. Enraged, the shark starts chasing after Peter. After several minutes of fighting and swimming away from the shark, Peter tries to escape by climbing up onto 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, the shark sinks to the bottom of the bay. The shark struggles until he's too tired to move. Passing fish begin to poke fun at him. Meanwhile, Polly and Peter reconcile and fall in love, thus Peter's wooing succeeded. They cuddle, and their bodies form a heart-shaped silhouette on the horizon.
