Hapi and his son Wow, the couple even sneezed "Hapiu!" The happy father and son of cans, in episode 52 of the first part, experienced the adventure of orchard hometown and garbage island, and returned to urban life in episode 52 of the second part. The place where Hapi and his son live is a super metropolis, as dazzling as a supermarket. Hapi apartment has shopping racks, machines sold by beverage and energy companies, fresh-keeping hospitals, bubble primary schools, straw amusement parks and so on. Dad Ha is a small clerk in an energy company, specializing in the production of "super energy drinks". This magical drink, which can produce many special functions such as invisibility, flight and deformation, brings convenience and happiness to the life of father and son and citizens in supermarket city, but also brings a lot of troubles. Pi's son goes to Paopao Primary School. He had many unexpected interesting things with friends of different shapes and personalities, and mingled with equally interesting parents from time to time, which also brought a dumbfounding influence on the life of the father and son. ...

The biggest trouble is the beer barrel thief I met on the garbage island. He is very greedy. In order to get super drinks, he disguised himself, approached Hapi and his son, and provoked a thrilling "Wulitou" drink war.

Inspired by Pi's son, Ha Da made the "king of drinks" with the most peculiar function, and won an unexpected prize-refrigerator villa, which has a large living room where you can play football, a restaurant that serves luxurious food all day, a living room with a huge TV screen, and meticulous service from Tetra Pak housekeeper and bottle maid ... The father and son who were originally in financial difficulties lived a good life of "having whatever they want".

The fresh and comfortable luxury villa life made Father Habib have a different happy experience and encountered unexpected new troubles. How can the life of rich people become more and more depressed? Why are villas always threatened by black hole pollution? What's more troublesome is that the thief who stole the beer barrel always snooped strangely ... Fortunately, with the help of the jelly elf, the father and son solved the problem of "rich disease".

The problem of black hole pollution made the father and son leave the refrigerator villa, but this beautiful and affluent life made Hapi and his son realize that simple family ties are much more important than material enjoyment!

"Happiness" is the main theme of their lives. No matter how much trouble they encounter, father and son are always happy and optimistic to meet the next big trouble.
