Buru Buru Dog (ぶるぶるどっぐ), created by Hikaru Suemasa for San-X in 1999, is named after the Japanese onomatopoeia buruburu, meaning "to tremble". This tiny, fluffy white dog has teary round eyes and a tail that turns blue when frightened and pink when in love. Gentle but extremely timid, he shivers constantly—even when he's happy. He dislikes rain, enjoys playing hide-and-seek, wears his signature polka-dot underwear, and loves jiggly strawberry jelly. His closest companion is a little chick.
