Captain Underpants and the Perilous Plot of Professor Poopypants (Captain Underpants #4) — Dav Pilkey
Quick Verdict: Professor Poopypants might have the single greatest villain name in children's literature — and this is the book where Pilkey leans hardest into name-based chaos.
Book four introduces a new science teacher whose name is so humiliating he tries to force the entire planet to adopt ridiculous monikers via the Name Change-O-Chart 2000. George and Harold resist; hilarity and Flip-O-Rama fight sequences ensue. Pilkey's art stays deliberately crude — smudgy line drawings that look like they were scrawled during detention — which is exactly the point. The grosser it looks, the more kids trust it. This is the volume that cemented Captain Underpants as the anti-establishment choice for primary school rebels.

Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy Part 1: The Night of the Nasty Nostril Nuggets (Captain Underpants #6) — Dav Pilkey
Quick Verdict: Pilkey splits one story across two books here, which sounds like a cash grab until you realise he's teaching serialisation to kids who think reading is optional.
Melvin Sneedly's science fair invention — a robot designed to enlarge human intelligence — backfires spectacularly when a rogue booger enters the equation. Cue the Bionic Booger Boy, a snot-powered villain who requires two full volumes to defeat. The cliffhanger ending is genuinely suspenseful if you're eight, and the margin gags ("TreeHouse Comix Inc. Presents") remind kids that making your own comics is always an option. Pilkey's genius was always structural: the Flip-O-Rama fight scenes train hand-eye coordination while delivering cartoon violence that would make Roald Dahl proud.

Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy Part 2: The Revenge of the Ridiculous Robo-Boogers (Captain Underpants #7) — Dav Pilkey
Quick Verdict: The payoff half of the Bionic Booger Boy saga — and proof that Pilkey could sustain a joke across 250 pages without losing steam.
Part Two escalates the snot-based mayhem with the arrival of the Robo-Boogers, mechanical mucus monsters that terrorise the city while George and Harold scramble to reverse-engineer Melvin's invention. The resolution involves time travel, mistaken identity, and a giant pair of robotic nostril plungers — standard Captain Underpants fare, which is to say gleefully unhinged. Pilkey never forgets that his audience is kids who've been told to sit still all day; these books are permission to mentally check out and giggle at bodily functions.

Captain Underpants and the Wrath of the Wicked Wedgie Woman (Captain Underpants #5) — Dav Pilkey
Quick Verdict: The villain is a psychokinetic schoolteacher armed with weaponised underwear — and somehow it's not even the weirdest thing that happens in this book.
George and Harold's comic-book creation, Wedgie Woman, springs to life when their mean teacher Ms Ribble gets hypnotised and gains actual superpowers. The ensuing battle involves giant robots, a stolen Robo-George and Robo-Harold, and a climax that parodies superhero origin stories while also being one. Pilkey's meta-awareness — the boys are constantly aware they're in a book, and occasionally annoyed by the narrator — gives the series a Monty Python energy that British kids' authors like Andy Stanton clearly studied.

Mr Gum and the Goblins — Andy Stanton, illustrated by David Tazzyman
Quick Verdict: If Captain Underpants is American gross-out, Mr Gum is British bonkers — same energy, different accent, more invented words.
Stanton's second Mr Gum book pits the town of Lamonic Bibber against a horde of filthy goblins who live in a bathtub and smell like rotting vegetables. The prose is relentlessly playful — Stanton invents words mid-sentence and addresses the reader directly ("Oh, you don't believe me? Fine, don't") — and Tazzyman's scratchy illustrations look like they were drawn by a caffeinated Year 6 student. The Mr Gum books are what happens when a British comedian writes kids' fiction: panto logic, absurdist detours, and a hero (Polly) who's smarter than every adult in town.

Mr Gum and the Secret Hideout — Andy Stanton, illustrated by David Tazzyman
Quick Verdict: The plot is secondary to the vibes, which are: delightfully unhinged, determinedly silly, and allergic to good behaviour.
Mr Gum discovers a mysterious hideout and immediately uses it for nefarious purposes, because he's Mr Gum and that's what he does. Stanton's narration frequently derails itself to argue with the reader or complain about the characters, which sounds chaotic on paper but works brilliantly in practice — it's the literary equivalent of a kid making up a story on the fly and loving every second. The Mr Gum books share Captain Underpants' core insight: kids don't want tidy narratives, they want permission to mess around.

Mr Gum and the Dancing Bear (Mr Gum #5) — Andy Stanton, illustrated by David Tazzyman
Quick Verdict: A Russian bear named Padlock wanders into town and immediately becomes the most beloved character in the series — which tells you everything about Stanton's priorities.
Book five introduces a tap-dancing bear with a tragic backstory (sort of) and a penchant for showmanship. Mr Gum, naturally, tries to exploit him; Polly and her friends resist; chaos follows. Stanton's dialogue is peak nonsense — characters shout things like "YOBBOS!" and "You're nothing but a lazy old SAUSAGE!" — and the fourth-wall breaks are so frequent the wall barely exists anymore. If your kid loved Captain Underpants but aged out of the toilet humour, Mr Gum is the next logical step: same absurdist energy, slightly more sophisticated vocabulary, equally disdainful of authority.

Both series treat reading like a playground — somewhere to run around, break rules, and giggle at things adults pretend aren't funny. That's not chaos; that's good pedagogy disguised as bad behaviour. Shop all Coffee Table Books at Patina Paperbacks →

Are the Mr Gum books similar to Captain Underpants?
Spiritually, yes — both series weaponise absurdist humour and illustrated chaos against reluctant readers. Mr Gum skews slightly older (ages 8–11 vs Captain Underpants' 7–10) and swaps American gross-out for British nonsense, but the core appeal is identical: permission to giggle at authority figures and enjoy books that refuse to behave.
Do I need to read Captain Underpants in order?
Not really. Each book is self-contained enough that kids can jump in anywhere, though the recurring villains (Professor Poopypants, Wedgie Woman) are funnier if you've met them before. The Bionic Booger Boy two-parter (books 6 and 7) is the only true cliffhanger situation.
What age group are these books aimed at?
Captain Underpants targets ages 7–10; Mr Gum skews 8–11. Both series work best for kids who've been told reading is "good for them" and are deeply suspicious of that claim — these books prove that reading can be gleefully, unapologetically silly.
Are these books appropriate for school libraries?
Honestly, that depends on the librarian. Both series have been challenged for potty humour and "disrespect for authority," which is exactly why kids love them. If your school tolerates Roald Dahl, these should be fine — though you might get a note home about the word "Poopypants."
