(at around 21 mins) While Baby Mumble is with the Skuas, a small black bow can be seen on Mumble's chest. However, when Mumble falls into the crack in the ice, the bow disappears. When the birds fly away, Mumble rolls to the side and begins to cry, with his bow visible again.

Elephant seals are dangerously territorial. Not even penguins would have been left alive by them.

Penguin chicks cannot stand on the ice immediately after hatching nor do they hatch fluffy and dry.

Emperor penguins don't mate for life as implied in the film. They're monogamous - but typically only for a year. Fidelity between years is about 15%.

Memphis's egg should have frozen before he even got to it.

(at around 1h 8 mins) When the amigos, Lovelace and Mumble are overlooking the land of elephant seals and ask if they are penguin eaters, and one of the others says they are herbivores, kelp suckers. This is untrue as elephant seals are carnivores and some are omnivores. But none are just herbivores.

(at around 11 mins) When Memphis and Norma Jean find each other in the crowd (when the females are returning), one penguin in the center of the screen walks through another penguin.

(at around 41 mins) When Mumble and the Amigos are outrunning the avalanche, Mumble hangs in mid-air for a few seconds, and Ramon grabs onto Mumble from behind before they fall. Looked at closely, Ramon's flipper passes through Mumble's feathers right before they nose-dive down the slope.

(at around 1h 15 mins) When the Adelies and Lovelace are involved in the killer whale attack on the frozen buoy, Mumble surfaces. When he starts speeding up, there's no wake seen behind him.

(at around 1h 45 mins) During the end credits, there is a typographical error in the music listing for "My Way". It reads, "Performed b Robin Williams".

(at around 8 mins) When Mumble is born, Memphis says "woah" a little bit before Mumble's foot actually comes out of the egg.
