The place where Hapi and his son live is a super metropolis as dazzling as a supermarket. Dad Ha is a small clerk in an energy company who specializes in producing "super energy drinks". This magical drink, which can produce many special functions such as invisibility, flying and deformation, brings convenience and happiness to the lives of father and son and citizens of supermarket city, and also brings a lot of troubles. Pi's son is studying in Paopao Primary School. He and his friends with different shapes and personalities have had many unexpected interesting things, and their equally interesting parents have blended from time to time, which has also brought a dumbfounding influence on the lives of the father and son ...

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

Inspired by Pi's son, Dad Ha produced the "King of Drinks" with the most peculiar function, and won an unexpected prize-the refrigerator villa, which has a large living room where you can play football, a restaurant full of luxurious food all day, a living room with a huge TV screen, and the meticulous service of 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 has made Hapi and his son have a different happy experience, and they have also encountered unexpected new troubles. How can the life of the rich get more and more depressed? Why are villas always threatened by black hole pollution? What's more troublesome is that the beer barrel thief always makes strange snooping ... Fortunately, with the help of the jelly elf, the father and son solved the problem of "rich disease".

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