Chibi Maruko-chan (1990)

Meet Maruko, a sweet schoolgirl with a hefty dose of curiosity (and occasional laziness!). She sails through life in a cozy town alongside her loving parents, grandparents, and sister. Maruko has a band of loyal friends, including her closest pal, Tama-chan, but her playful and doting grandpa is at the heart of it all. Life is never dull in this charming series.
