In this film, Pom and his friends will learn that the lungs make sure the body is supplied with enough oxygen. It shows how air gets into the lungs, how oxygen is absorbed and transported in the body, and how carbon dioxide is then breathed out again. At the end of the film, Octavius the Octopus will recap the most important facts in a glossary.

With the simpler language and animated subplot, this version is particularly well suited for use in primary school.
