And with the help of his new neighbour Nilly, and Nilly's friend Lisa, Doctor Proctor's Fart Powder is ready to go worldwide! But ruthless twins Truls and Trym are determined to get hold of the powder for themselves.

Their plot to spoil the Doctor's plans sparks a fart-filled adventure involving a firework extravaganza, a trip to prison and an escaped anaconda.
