Will little penguins have altitude sickness when they move to the North Pole?

There will be no altitude sickness, but penguins are not allowed to go to the North Pole. Although penguins don't go deep into the hinterland of Antarctica, they do want to live in the cold waters near Antarctica. They can relax there because they have the best cold protection equipment I have ever seen. Penguins have feathers, which are tightly connected together like roof tiles to form a sealed and waterproof "coat", and there are layers of fluffy down underneath. The cute fat body also helps them keep warm. Penguins will suffer a lot if they want to migrate to the North Pole in the northern hemisphere, because if they want to get there, they must swim across the warm equatorial waters. You can imagine how uncomfortable they will be, just like you and me, running in the hot sun in ski suits. When we filmed the movie Frozen, I was surprised to find that in the Antarctic summer, even though it has never been warmer than the mild English winter, penguins have to make special efforts to cool themselves down. When we saw our first shot, the whole film crew laughed. We saw the emperor penguin clumsily throw himself on the wet and cold beach, cooling his abdomen and radiating heat with his bare pink flippers. Little penguins are more interesting. In order to cool off, they took a mud bath and came out looking like they had been soaked in melted chocolate. If penguins reach the North Pole and don't faint from heatstroke, they will bump into another group of black and white birds. They are puffins and look like penguins, but they will _ and penguins won't. Being unable to fly is also a good reason why penguins don't go to the North Pole, because they can't escape the capture of polar bears and arctic foxes. In summer, these animals often haunt nesting birds. In Antarctica, penguins don't have to worry about attacks on their nests. No carnivores live there, and none of the ancestors of wild animals can cross the turbulent and cold ocean to reach the South Pole. Some species of birds (ancestors of penguins) have lost the ability to fly because they no longer need to avoid predators. Penguin's wings become thick and short, like fins, which are used to paddle in the water. When taking aerial photos over Antarctica, I was lucky enough to see penguins swimming from the air. I immediately realized that penguins are flying in another way, flying in the ocean. That's one of the most beautiful things I've ever seen, just like watching underwater ballet. Everyone will think of penguins' clumsiness and stumbling when they walk, but only after seeing their elegant swimming posture will you realize that this cold southern sea is their natural home.
