Susuwatari (Japanese: ススワタリ, 煤渡り; "wandering soot"), also called Makkuro kurosuke (まっくろくろすけ; "makkuro" meaning "pitch black", "kuro" meaning "black" and "-suke" being a common ending for male names), is the name of a fictitious sprite that was devised by Hayao Miyazaki and Studio Ghibli, known from the famous anime-productions My Neighbor Totoro (1988) and Spirited Away (2001) where, in the former, they are identified as "black soots" in early subtitles, as "soot sprites" or "dust bunnies" in the Streamline Pictures English dub,[1][2] and as "soot gremlins" in the Walt Disney Studios English dubbed version.

Susuwatari are described and shown as golf ball-sized, pitch-black and fuzzy-haired beings with two large eyes and long, thin limbs.

They move by hovering around, but they can extend stick-like limbs from their bodies to do certain tasks, and can lift objects many times their own weight.

[4] After Sen is accepted among the staff of the bathhouse, chiefly by Kamaji and Lin, the Susuwatari become almost admiring of her,[6] and help her in their small ways.

[5] In 2022, Studio Ghibli and Lucasfilm collaborated on a Star Wars short for Disney+ where The Mandalorian character Grogu interacts with a band of dust bunnies that give him a flower as a gift.
