A little girl spends eight episodes asking strangers what "low fuel cost" means, and somehow that's the entire joke, delivered with the deadpan precision of a man who made his name on absurdist gag anime. The Heidi parody isn't trying to deconstruct anything or wink at you, it just commits to the bit with one voice actor playing a sheep with the same earnestness as a grandfather. You're not watching a commercial that became anime; you're watching a director weaponize a Nissan Note campaign into proof that the funniest thing on the internet doesn't need spectacle, just permission to be stupid in exactly the right way.

A curious little girl keeps putting the same question to everyone she meets: what does "teinenpi" mean? The word is a kanji term for fuel efficiency, and the eight short episodes were made as web advertising for the Nissan Note. The content runs far more freely than a typical ad would, spoofing the 1974 Heidi anime under Satoshi Fumihara, director of the gag series The World of Golden Eggs. Junichi Koumoto voices several parts, including Grandpa, Peter, Kurara and even the sheep. Beneath the gag-heavy surface lies an oddly charming oddity: a corporate advertisement that commits to being entertainingly weird rather than polished.
