Common Sense Note
Parents need to know that the main character has a stutter for which he is teased by a bully, but it becomes less noticeable around his friends and girlfriend. The same bully is a menace throughout the film, most disturbingly as he kidnaps the object of his romantic affection. When persuasion has failed, a character holds his breath to get his way. Depictions of animals roughly handled on the way to zoo captivity may trouble young animal lovers. Also, scenes of pursuit by leopard seals and killer whales are intense, probably more so than children under age 7 will want to watch.
The entire plot is predicated on Hubie getting back to Marina for mating season, so although nothing graphic is shown the topic is ever-present.
The main character is threatened by a bully, a leopard seal, and a pod of killer whales in suspenseful animated scenes that, at least in the latter two cases, convincingly mimic real threats on a penguin's survival.
A deep if lopsided friendship develops between two unlikely characters, causing one to risk his life for his friend's sake, even after he has been lied to. A developing romance is marked by loyalty and understanding in the face of teasing and threats from outside parties.
