Comic mysteries, spy capers and adventures packed with puns, for fans of Mango and Brash.

15 booksAges 5–11See the InvestiGators seriesLast reviewed June 2026

InvestiGators works because it's three things at once: a mystery, a spy caper and a relentless pun machine. A child who loves it tends to love the combination: a plot to solve, gadgets and disguises, and a joke buried in every other panel.

The list below leans into that. It opens with the books closest to Mango and Brash's world, including their own spin-off, then broadens to other funny comic mysteries and high energy adventure series with the same quick wit. Most are full colour graphic novels pitched around seven to ten, with a couple of slightly older options for a reader racing ahead. If the appeal was the detective work, the silliness, or both, there's a next read here.

  1. Agents of S.U.I.T.

    Literally the same universe: the S.U.I.T. spin-off, and the most direct next read of all.

  2. The Bad Guys

    A hugely accessible, very funny graphic novel about four scary-looking animals trying to prove they can be heroes. It is one of the strongest modern gateway series for reluctant readers moving into longer independent reading.

  3. Dog Man

    Dog Man is a half-dog, half-police-officer superhero created by accident, and one of the best-selling children's series in history. Brilliantly designed for reluctant readers: fast, funny, full of interactive flip-o-rama pages, and so packed with action that even the least bookish child will demand the next one.

  4. Boss of the Underworld: Shirley vs the Green Menace

    A fizzing, full-colour comic adventure about a girl who falls into the Underworld and is unexpectedly treated as its chosen hero. It is especially strong for Bunny vs Monkey, Dog Man and Phoenix Comic readers who want big laughs, strange creatures and fast visual storytelling.

  5. Kitty Quest

    A fast, daft, monster-slaying cat adventure that feels like a younger graphic-novel bridge between Dog Man, Bunny vs Monkey and fantasy quest stories. Excellent for reluctant readers who want jokes, monsters, maps, swords and very little friction.

  6. Bunny vs Monkey

    A riotously funny forest comic about Bunny trying to keep the peace after Monkey crash-lands and begins causing total mayhem. A near-perfect bridge from silly picture books into independent graphic-novel reading.

  7. Pablo and Splash

    A bright, very funny full-colour graphic novel about two opposite-personality penguin best friends accidentally time-travelling to the age of dinosaurs. It is a strong fit for Bunny vs Monkey, Dog Man and InvestiGators readers ready for a gentler but still zippy comic adventure.

  8. Star Cat

    A brilliantly silly space-comedy graphic novel about Captain Spaceington and the crew of the SS Star Cat. Ideal for readers who like absurd sci-fi, quick visual jokes and Phoenix-style comic energy.

  9. Max and Chaffy: Welcome to Animal Island!

    Max discovers a hidden island full of talking animals and meets Chaffy, an immediately loveable creature who becomes his best friend. Jamie Smart's signature zany energy and expressive visuals make this the best new graphic novel series for reluctant readers.

  10. Hilo: The Boy Who Crashed to Earth

    A fast, funny, big-hearted sci-fi graphic novel about an ordinary boy, a brilliant girl and a robot kid who crashes to Earth in his underwear. It is one of the strongest post-Dog Man gateways into longer, more story-driven graphic novels.

  11. Donut Squad: Take Over the World!

    A gleefully ridiculous Phoenix comic-book collection about donuts with big plans for world domination. It is built for children who want joke-dense, colourful, fast-reading comic chaos.

  12. The First Cat in Space Ate Pizza

    A gloriously daft sci-fi graphic novel about a bioengineered cat sent to save the moon from hungry space rats. It is fast, funny and very accessible for readers who like Dog Man, InvestiGators and big absurd visual jokes.

  13. Barb the Brave

    A fast, funny fantasy graphic novel about a small but fearless warrior and her yeti best friend. Great for Dog Man, Bunny vs Monkey and Hilda readers who want more monsters, swords and quest energy.

  14. Unfairies

    A frantic, full-colour fairy graphic novel that turns sweet fairy clichés completely upside down. It is a strong fit for Bunny vs Monkey, Dog Man and InvestiGators readers who want big jokes, miniature battles and a scrappy fantasy quest.

  15. Dungeon Runners: Hero Trial

    An award-winning fantasy debut where dungeon-running is a televised sport and the underdog is a gnorf with something to prove. Larwood (of Podkin One-Ear) and Todd-Stanton give Dog Man / InvestiGators readers a high-fantasy alternative without sacrificing pace or jokes.
