While Mei-chan is playing in the backyard one day, she befriends a baby neko-bus with a piece of caramel. The Konekobus repays the favour that night by taking Mei to a clandestine meeting of forest spirits. Things get scary when the Konekobus disappears like the Chesire Cat, but it's not long before Totoro shows up and new friends are made.
It's a shame Studio Ghibli never released this original short, because it should be required watching for anyone whom enjoyed My Neighbour Totoro. Obviously there's not much story to develop in 15 minutes, but Mei To Konekubasu delivers more Totoro, more forest spirits, and lots more Nekobus. Unfortuneately this can only be seen in the Ghibli museum in Mitaka, Japan.
