There was a bear living in the forest, and everyone called him "Mr. Big Bear.". Mr. Big Bear's breakfast shop sells breakfast on time every day.

Mr. Big Bear never slept or was late because he had a secret weapon— the Cuckoo Alarm Clock. This cuckoo arrives at 5 a.m. every morning and says "Cuckoo! Cuckoo! "I called Mr. Big Bear up on time, and the voice was loud and bright, and Mr. Big Bear liked this alarm clock very much.
However, this cuckoo is becoming less and less fond of Mr. Big Bear, why? It turns out that Mr. Big Bear has a bad habit of not loving cleanliness. His home is full of dust, the dirty clothes and smelly socks he wears are littered everywhere, and the garbage has not been taken out for many months. Therefore, the cuckoo often complains to Mr. Big Bear, hoping that he can clean up well, but Mr. Big Bear completely ignores it.
One day, the cuckoo smoked too much dust on weekdays and had a bad throat, and decided not to help Mr. Big Bear anymore, so he flew away.
"What now?" If you don't wake yourself up without an alarm clock, you will definitely oversleep, so that the animals in the forest will not have breakfast. So, Mr. Big Bear began to look for a new alarm clock, and he thought to himself, "It should be easy to find!" Sure enough, he immediately found a sparrow to come as his new alarm clock.
Mr. Big Bear was very happy, and he told the sparrow to wake him up at 5 a.m., and then went to bed with peace of mind. At 5 o'clock the next morning, the sparrow tried to get Mr. Big Bear up, but the sparrow's voice was so small that even Mr. Big Bear's purr was louder than it! Mr. Big Bear did not hear the sparrow's call at all and continued to sleep.
In this way, by the time Mr. Big Bear got up, it was already 12 noon, and he was blamed by all the animals waiting in line to buy breakfast. Mr. Big Bear felt that it was not okay for the sparrow's voice to be so small, and decided to change the alarm clock, and this time he had to check first to see if the sound was loud enough.
Luckily, Mr. Big Bear found a new alarm clock – pigeons. The pigeon's voice was a little muffled, but it was quite loud, so Mr. Big Bear said yes to the pigeon, told him to get up at 5 o'clock in the morning, and went to bed.
The next morning, nearly 5 a.m., the pigeon was preparing to get Mr. Big Bear up when it occurred to him that he had to do another job, to deliver letters as a postman. So the pigeon decided to deal with the delivery of the letter first, but the destination of the letter was very far away, and the pigeon flew for a long time before it arrived, and when it returned to Mr. Big Bear's house, it was already 12 noon. Mr. Big Bear did not sell breakfast this day, and everyone was even more angry.
Mr. Big Bear himself was very angry: "Pigeon, why don't you tell me about your other work first?" That's irresponsible! "Mr. Big Bear decided to say goodbye to the pigeons and find a more suitable bird to use as an alarm clock. This bird must not only be loud, but also not bad.
Luckily, Mr. Big Bear found the owl. The owl is not only loud enough, but also guarantees that he will only concentrate on Mr. Big Bear's job. Mr. Big Bear was relieved, he told the owl about the time to get up, and went to sleep.
It wasn't long before Mr. Big Bear heard the owl "grunting" and he looked at the clock, and it was only 11 p.m. It turned out that the owl was a nocturnal animal, and at night it would involuntarily want to make a sound, and Mr. Big Bear could not stop him, but had to listen to him grunt all night. I don't know how long it took for the owl to finally stop barking, and Mr. Big Bear could finally sleep well.
But when he was full of sleep and opened his eyes to see the time, how could it be 12 noon again? Mr. Big Bear found the owl sleeping! On this day, Mr. Big Bear did not sell breakfast, and the animals were already disappointed and did not want to visit big bear breakfast restaurant again.
Mr. Big Bear was very upset and thought, "This kind of thing didn't happen when the cuckoo was there before, so why did the cuckoo leave?" Is it because I don't like to be clean and don't clean, so... Good! I know! ”
Mr. Big Bear rushed home, and after some effort, Mr. Big Bear's home became so clear! Then, he went to the forest to apologize to the cuckoo and promised that he would definitely clean up every day in the future and keep the environment clean. The cuckoo saw Mr. Big Bear's sincere look and promised to continue acting as his alarm clock.
From then on, every morning at 5 o'clock, "Cuckoo! Cuckoo! A familiar voice would sound, and Mr. Big Bear quickly got up and headed for the breakfast shop. He no longer had to worry about being late, and he also understood the importance of cleanliness!
