The problem of the little whale, the problem of the little whale

? The little whale and the three little goldfish are inseparable friends. They had a good time together every day and didn't go home until their mother called them.

One morning, the little whale and three little goldfish played together again. Look, they are playing hide and seek! The little goldfish hid behind the big stone. It didn't hide there. Apparently, it was discovered by a small whale. Little whale didn't know where the other two companions were hiding, so he looked at Huang Huang's expression with searching eyes, trying to get some information, but when the information didn't come out, the problem was discovered.

He found that although the little goldfish had nostrils, it did not breathe through them, but through the cheeks on both sides. But why do your nostrils grow on your head? Apparently a curious little whale, he called out two hidden little goldfish Cong Cong and Heihei and asked them, but they didn't know.

Little whales obviously think that turtles are longevity stars, and they must know the answer. So he took his friend to the old tortoise's house to ask. The old turtle doesn't like reading at all, but only plays pranks. No, there is always a piece of paper that says "I am a bad person" on the black back of the old turtle!

The old turtle didn't even know this common sense, which made the little whale a little disappointed. He went to the little crab's house again, still trying to find the answer. Although little crab has several books to read, they are all comic books, and he doesn't know.

The little whale was obviously a little discouraged, but he didn't want to give up the problem, so he came to the knowledgeable octopus family. The little octopus loves books so much that everyone calls him "doctor octopus". When the little whale asked, doctor octopus smiled and said, "Why didn't you come to me first?" Obviously, hey! There is a door, and the little octopus must know it. Doctor octopus told him, "Look, if your nostrils are above your mouth, when you breathe, your head has to face up. It would be terrible to flash your waist. If your nostrils are on your head, you can breathe as soon as you surface! "

Oh! I see! The little whale suddenly realized.
