Body Troopers (Norwegian: Jakten på nyresteinen), also known as Chasing the Kidneystone, is a 1996 Norwegian children's film directed by Vibeke Idsøe, starring Torbjörn T. Jensen and Kjersti Holmen.
Eight-year-old Simon shrinks himself to microscopic size in order to travel through his ailing grandfather's body in search of a kidney stone.
On his journey he meets anthropomorphic characters such as the taste buds, white and red blood cells, and the vocal cords.
[2] The film is based on the book Jakten på nyresteinen, also written by Idsøe.
