Today is gone, tomorrow is gone! "Little Bunny Foo Foo's" origins are unknown, but it has become a popular children's folklore. It is also known as "Little Rabbit Foo Foo" and "Little Bunny FuFu." This is a repeating song that concludes the narrative. The melody of Little Bunny Fufu is similar to that of Little Bo Peep. Both songs are about lost lambs that are found by their mothers. However, while Little Bo Peep's mother finds her by following the sound of sheep bells, Little Bunny Fufu's mother finds him/her by looking for his/her footprints in the snow. There are several theories about how this folktale came to be. Some say it was created by an American soldier during the Japanese occupation of World War II. He wrote it as a way to teach Japanese children English words such as "bunny," "fufu" (Japanese for "stuff"), and "fu" (English for "eat"). The soldier named the song "Little Bunny Foo Foo" and it caught on among the occupied people. Other theories claim that the song is much older and originated with humans. Some historians believe they can find evidence of its origin in ancient Egypt where children would sing stories about ducks and rabbits to help calm their parents down when they were afraid.
