One day, grandma is going out of town. Mimi went to the station to see her off. When she got home, she found a lovely panda father and son. When the giant panda learns that Mimi has no parents, she will be Mimi's father and Mimi will be the fat mother of the little panda.
The next day, Mimi went to school, and the little panda wanted to go to school with her. Mimi takes the fat boy to school as a doll. However, the teacher didn't allow Mimi to bring the doll to the classroom, so Mimi had to put the fat boy outside. The greedy fat boy ran to the school kitchen and caused an uproar. Fortunately, he escaped.
The policeman who didn't trust Mimi at home went to Mimi's house to inspect, but fled because he found the panda defeated. After that, he rounded up the panda with a large number of police. It turns out that the panda father and son ran out of the zoo, and the person who caught them could get a bonus. The panda father and son knocked down the man who wanted to catch them with divine power, only to find that the fat man was gone!
Later, people found the fat boy in the river, but the dam was not far ahead. The laid-back fat boy had no idea of the immediate danger, and Mimi jumped into the water to save the fat boy. Just as the dam gate switch rusted again, Papa Panda closed the gate with divine power, and Fat Man and Mimi survived. Both the panda father and son have become public figures, and the panda father still goes to work by tram!
The circus leader went to Mimi's house to look for the lost tiger. Mimi thinks they are thieves and is very excited, because Mimi has never seen a thief! However, the poor circus leader thought that the panda and his son were monsters and scared him to run away.
Mimi and the panda have dinner together, but the fat boy finds that his dinner has been stolen and his things have been stolen. Finally, they found a little tiger on the fat boy's bed. Xiaohu lives happily with them.
The next day, the fat man and the tiger went shopping with Mimi, while the fat man and the tiger ran around by themselves. Mimi looked for them everywhere, but she couldn't find them. When she met her classmates who wanted to see the circus in town, she followed them to the circus, only to find that a tigress had caught the fat boy! However, the tigress smiled at Mimi. It turns out that the tigress is the mother of the tiger! Since then, Mimi and circus animals have become good friends.
When I got home, it began to rain heavily outside, which caused a big flood. Mimi received a letter from the circus for help. She came to the bedside with food to save people. When I arrived at the flooded town, I found that the circus members had abandoned the animals and fled by themselves. Mimi was very angry and ran to the place where the animal was trapped and rescued it. In the process of rescue, the naughty fat man and tiger accidentally activated the train, the train running all the way, and finally drove to the road! It was about to hit the mayor's office. Papa Panda used his magical power to stop the train and solve the crisis.
