Doctor Proctor's Fart Powder by Jo Nesbø

4.0

After Nilly moves he and Lisa become fast friends. Together they help their neighbor Doctor Proctor to sell his remarkable invention, a tasteless powder that will make you fart magnificent farts. When Doctor Proctor and Nilly get arrested, Lisa works to make sure the fart powder is safe and Nilly makes a spectacular escape.

The humor of this reminded me a lot of Captain Underpants. There were several times that I snorted and laughed while reading. It had the perfect amount of absurd.
