The story revolves around Ma Xiaotiao, a third-grade elementary school student. Ma Xiaotiao is no ordinary child—he could jump the moment he was born! At his one-year-old "抓周" ceremony, the fiery-tempered Ma Xiaotiao "jumped" sky-high, astonishing everyone. In third grade, Ma Xiaotiao is always surrounded by his close friends: the sharp-tongued "Monkey" Mao Chao, the gluttonous and sleepy "Penguin" Tang Fei, and the incredibly strong "Hippo" Zhang Da. Of course, there's also An Qi'er, who unconditionally idolizes Ma Xiaotiao. As for Ma Xiaotiao's own idol, it's the beautiful, smart, and academically excellent "ballet star" of the class, Xia Linguo. Ma Xiaotiao also has his rivals in class—his deskmate Lu Manman and the study committee member Ding Wentao. Lu Manman loves to keep Ma Xiaotiao in check, while Ding Wentao always pours cold water on his ideas. When conflicts between Lu Manman and Ma Xiaotiao erupt like a collision of planets, there's also Teacher Qin, whom Ma Xiaotiao fears the most, because Teacher Qin loves to call Ma Xiaotiao's parents. Usually, it's Ma Xiaotiao's toy designer father, Ma Tianxiao, who gets summoned. Ma Tianxiao is no less of a prankster than Ma Xiaotiao himself—fighting over chicken legs at the dinner table is the perfect example.
