Our view
“Captain Underpants and the Perilous Plot of Professor Poopypants” is Dav Pilkey’s silly humour at full throttle. This time a mad scientist with a ridiculous name arrives as the new science teacher at the boys’ school, and the pupils cannot stop laughing at him. Some readers count him among the most memorable villains of the whole series. Children who already love the earlier books will want this one too.
