Thank you! 35th Anniversary of the Anime: Laugh, Sing, and Bring Good Fortune! New Year's 1-Hour Special - S0.E32

"The next episode will be a one-hour special to celebrate the 35th anniversary of the anime. There will be a story about Maruko and her friends becoming members of the Drifters, and a special episode where they hold a Chibi Maruko-chan song festival and sing all kinds of songs. I wonder what songs they'll sing, hehe, it's still a secret. Look forward to it."
