Mei is eating a caramel on one very windy day, when suddenly a whirlwind appears and starts chasing her. The whirlwind turns out to be a baby cat bus. Mei offers the kitten a caramel and the two become friends. That night, the baby cat bus visits Mei. Letting Mei ride inside him, he leaps out into the sky. They head for the midnight forest full of ghosts. Other cat buses large and small have also gathered together.
Unfortunately the movie Mei and the Kittenbus is not yet available on HBO Max.
