The Catbus
The Catbus is a fictitious character from Studio Ghibli's My Neighbor Totoro. It's a huge, happy-go-lucky twelve-legged cat with a hollow body that doubles as a bus, replete with windows and fur-covered seats and a large bushy tail. While whatever this monster is may sound weird, and no one knows where it came from, crawl inside and you'll find warm, fluffy seats that far outweigh harsh plastic. It will also transport you to your destination while leaving no trace.
When Mei, Satsuki, and Totoro are waiting for Tatsuo Kusakabe's bus, the Catbus emerges on the forest road. The females make a random noise of surprise after the bus speeds up and then backs up, meowing with its bright car light eyes and smiling like the Cheshire Cat. To function as tail lights, mice with luminous eyes are taped next to the destination sign. It always has a big smile on its face and may come and disappear at any time. It is capable of traveling to any location desired by its passengers.
Because of the character's popularity, it has inspired a spinoff film, toys for children, an art car, and a position in the Ghibli Museum. Many chain fashion stores, like Hot Topic, sell goods featuring Catbus and other well-known Studio Ghibli characters. That's why it is listed as one of the most popular anime cats of all time.
