"Little Bunny Foo Foo" is a children's poem and song. The poem consists of four-line sung verses separated by some spoken words. The verses are sung to the tune of the French-Canadian children's song "Alouette" (1879), which is melodically similar to "Down by the Station" (1948) and the "Itsy Bitsy Spider". The person performing the song usually includes hand gestures, e.g. for "scooping" and "bopping".
The song has many different variations and is often passed on as childlore. Beverly Cleary's 1970 children's book Runaway Ralph mentions "Little Rabbit Fru-Fru" as a song heard at summer camp, and a 1970 issue of The New Yorker acknowledges "Little Bunny Phoo Phoo, a character in a children's story."
