Chibi Totoro is the smallest of the three totoros. He is white and sometimes see-through.

He is the first of the totoros that Mei sees in the yard. She follows him around, watching through the hole in a rotted-out bucket. When he disappears under the house, Mei stoicly waits for him to reappear.

Satsuki doesn't meet the Chibi totoro until the moonlight dance in the garden.
