In the grand nature, there is a city called ChiChi Land that is made of blocks. In this city, lively blocks (ChiChi blocks) live happily with Little Figures. ChiChi blocks have the ChiChi power, and can transform or combine into different things from props to big buildings. On the contrary, puny Little Figures have smart minds. Those two groups help each other and live happily in the magic ChiChi Land.
