Pica Pau is the Brazilian Portuguese name for Woody Woodpecker, the cartoon woodpecker created in 1940 and long shown in Brazil with a popular local dub. The phrase dorme filhinho, meaning sleep little one, circulates in Brazil as a short voice clip detached from any single scene, shared on soundboards and in messaging groups for bedtime jokes. Its appeal comes from that familiar dubbed voice and the universal lullaby wording, so Brazilian users keep reusing it for children, pets and tired friends long after the cartoons first aired.
