- When Hunter asks if any of the penguins have ever tasted penguin, Skipper and Kowalski look straight at Rico, who just looks slightly confused. Rico did have his mouth over Skipper's flipper when he was getting rid of the time bomb in All Choked Up. Technically he did not eat flesh.
- While in Antarctica Julian built ice sculptures of Mort, Maurice, and his throne
- This is the 2nd appearance for Cecil and Brick.
- Private makes a reference to the 'Keep Calm and Carry On' poster from World War 2 Britain.
- King Julien makes a reference to the "Do A Barrel Roll" meme.
- When Skipper says,Private don't be a hero! don't be a fool with your life!" He is saying a part of a song called "Billy Don't Be a Hero"
- This is the 3rd appearance of the submarine, This is, however, the first time it's been breached and destroyed by sinking to the bottom of the ocean, it is unknown how the penguins got back to New York with Julien. It's likely they swam given how Private and Hunter reached Antarctica.
- It was possible that if the Penguins had been carrying see-through duct tape, they could've stopped the sub from flooding before the windshield's breach could cause critical water levels.
- Private breaks the fourth wall during the feast when Hunter throws him in the air and he winks at the audience.
- Maurice, Mason, Phil and Marlene do not appear in this special.
- In the promo. When hunter roars at Private (they were playing) the creators made it look like private wet himself when he really spilled his lemonade.
- Mort appears briefly and thought the torpedo was a banana and attempted to blend it only for it to explode with mort shouting "WHY BANANA"
- Hunter said yay me similar to London Tipton (Brenda Song) from The Suite Life of Zack and Cody.
- Antagonist: Cecil and Brick (in the beginning), Hunter's Father (until the end), and Leopard Seals
- Julian considers the torpedo tubes in the penguin's sub to be his "royal nappy tube" it also makes him feel like a "handsome vampire"
- Hunter and her dad are the only leopard seals that can say anything other than "food"
- The Emergency evacuation launcher from Night and Dazed makes a reappearance
- Julian didn't die of hypothermia
- The leopard seal recipe for penguin is to eat the penguin alive
