In a whimsical 14-minute short film exclusive to the Ghibli Museum, viewers are immersed in the enchanting tale of Mei and her companion, the kittenbus—a miniature offspring of the beloved catbus from 'My Neighbor Totoro.' With Mei being just the right size to journey with the kittenbus, they embark on a magical escapade, causing playful dust devils instead of swaying vast rice fields. Their nocturnal adventure leads them into a mystical forest teeming with an array of cat-themed vehicles, including buses and trains, where they encounter Totoro and kindred spirits bound for a colossal catliner. As the majestic liner sets sail into the skies, the kittenbus safely returns Mei home, concluding their extraordinary journey.
