Created as a promotional piece for the Nissan Note, this web animation enjoys considerable creative freedom. It centers around a young girl who relentlessly asks people about the significance of "Teinenpi," a term denoting low fuel usage. The project humorously reimagines the well-known 1974 anime Heidi, directed by Satoshi Fumihara, famous for the comedic series The World of Golden Eggs. Voice actor Junichi Koumoto brings life to multiple roles, such as Heidi's Grandpa, Peter, Kurara, and even the sheep.
