This song is to the tune of Frere Jacques.
Watermelon, watermelon (make shape of watermelon with hands)
Papaya, papaya (make shape of papaya with hands)
Banana-nana-nana, banana-nana-nana (make swinging motion)
Fruit salad, fruit salad (put your hands on your hips and swing them around)
You can do this song with any fruits!
