Doctor Proctor's Fart Powder is a series of children's novels by Norwegian author Jo Nesbø, illustrated by Mike Lowery. The first novel in the series was Nesbø's first children's book, a contrast from the adult crime novels that he is known for. It was originally published in 2007 in Norway and 2010 worldwide.

The series spawned four sequels. The second book in the series, "Bubble in The Bathtub," was published in 2008 in Norway and 2011 worldwide. The third book, "Who Cut The Cheese?" (known as "The End of The World. Maybe." in Norway) was published in 2010 in Norway and 2012 worldwide. The fourth book, "The Magical Fruit" (known as "The Great Gold Robbery" in Norway) was published in 2012 in Norway and 2014 worldwide. The fifth book, "Silent (but Deadly) Night" (known as "Can Doctor Proctor Save Christmas?" in Norway) was published in 2017 in Norway and 2018 worldwide. On October 16, 2018, a box set of the preceding books was released.


The series is about an eccentric professor in Oslo, Norway who is waiting for his big break. He is soon befriended by Nilly, a quirky boy who is his new neighbor and his friend Lisa. Most people don't care much for Doctor Proctor's inventions, but Nilly and Lisa become obsessed with his latest invention, a powder which makes the user fart odorless farts. Doctor Proctor builds upon this invention and creates the "Fartonaut Powder," a powder that makes the user fart so powerfully they blast off into space. Doctor Proctor and the kids team up to deal with threats later in the series such as thieves, evil dictators, and aliens, using the powder and some of Doctor Proctor's other inventions to save the day.

Eleven year old Nilly has just moved to Oslo, Norway, and becomes friends with his neighbor Lisa and an eccentric professor named Doctor Proctor. Most of his inventions are unsuccessful, but he makes his big break when he invents a powder that makes people fart, and later a powder that makes people fart so hard they blast off into the sky. Nilly and Lisa sell the first type of powder to kids at school and become popular. Later Nilly uses the powder to get revenge on the school bullies, Truls and Trym Thrane, by giving them the second type, which causes them to fart up into a tree. Their dad finds out about this and sends Nilly and Doctor Proctor to jail. While they are arrested, Truls, Trym, and their dad break into Doctor Proctor's house and steal the rest of the fart powder, which is kept away in the scientist's cellar. Nilly and Doctor Proctor must escape from jail and meet up with Lisa so they can recover the powder in time for the Norwegian Independence Day celebration.

5Silent (but Deadly) NightOctober 2, 2018[5]ISBN 978-1534410008
The King of Norway sells the rights of Christmas to Mr. Thrane, much to everyone's dismay. This means that only "members" can celebrate Christmas, and anyone else who tries to do so will be arrested. Fortunately Doctor Proctor knows a semi-immortal man with magical abilities named Stanislaw who used to be Santa Claus, who is currently living in secret in Oslo. Nilly, Lisa, and Doctor Proctor must convince him to help them save the holiday. They attempt to deliver presents around the city of Oslo a few nights before Christmas, but are unsuccessful. They even break into Mr. Thrane's house, which gets his attention and causes him to call the police on them. Nilly, Lisa, Doctor Proctor, and Stanislaw run away to Stanislaw's secret base in the subway tunnels beneath Oslo. But soon the trio discovers that there is a legal document in the Oslo Courthouse that says that Stanislaw owns Christmas, and all they have to do is show it to the king of Norway and the rights of Christmas will be restored to Stanislaw before Mr. Thrane rips it up.


The series received generally positive reviews. One critic described the books as similar to the works of Roald Dahl and Lemony Snickett, and said that they can help to increase a child's creativity and imagination while doing so in a hilarious way.[6] Another described Nesbø's humor as zany, yet also farcical and matter-of-fact.[7] James Patterson also praised the original book, saying that "this terrific book will make you laugh, and cherish your friends, and value fair play." SLJ said that "(the book) will have no trouble enticing fans of Captain Underpants and the Wimpy Kid."[8]


Doctor Proctor’s Fart Powder was shortlisted for Ark’s Children’s Book Award (Arks barnebokpris) for ‘Best Children’s Book’ 2007 and was selected for The Richard and Judy Children’s Book Club in 2011.[9]

Film Adaptations[edit]

In March 2014, the first book in the series had a live-action film adaptation directed by Arild Fröhlich.[10] It is only available in Norwegian, although an unofficial English dub was made in October 2014. The film received mixed reviews.[11] However one critic stated that "(it's) a wonderful and subversive kids movie where parents are good-hearted but wholly absent and the children have to rely on their own wit and ingenuity to bail themselves from sticky situations. The film recalls the best made-for-kids movies of the 80’s and I do not believe it’s a happy accident that the absent minded Doctor Proctor bears a striking resemblance to Back To The Future’s Doc Brown. It’s the type of production that would be animated if it were an American film, yet it works so wonderfully as a live action movie."[12]

A sequel, Doktor Proktors Tidsbadekar (Bubble in The Bathtub), was released in 2015.
