Once Upon a Time... Life - The hormones

Peter and his friend Jumbo are playing tennis. The Master is observing the match from his monitor in the hypothalamus and is giving some instructions.

Globus explains to Hemo and Globine the functions of those little runabouts that cross their way every once in a while.
