'Plunct Plact Zuuum' was the first in a series of children's musicals shown in 1983. The special followed the lines of the programs 'Vinícius Para Criança – Arca de Noé' (1980), 'Arca de Noé II' (1981) and Pirlimpimpim ( 1982). Forbidden from doing the things they like and afflicted with the fears and anxieties inherent to their age, the children Aretha, Bruno Netto, Fabiano Vannucci, Marinela Graça Mello and Paulo Vignolo plan to run away from home to make their dreams come true. Right at the beginning of their journey, in search of a freer and more fantasy world, they meet a puppeteer who starts telling them adventure stories. Fascinated by the incredible narrative, the gang is excited by the arrival of a strange spaceship, assembled from scrap metal and forgotten objects. They board the ship and begin their adventure. The group also has the support of a strange being who travels in a baby carriage.
