Giant ants. P.A.N.T.S. (the organisation whose acronym is even worse than SUIT's). Green pivots the series into science fiction territory without losing any of the spy-comedy momentum, the insect-scale disaster gives the visual comedy a whole new register.

What’s it about?

The story.

Ants in Our P.A.N.T.S. marks the series' first genuine pivot into science_fiction territory: the threat this time is not a criminal organisation but something more absurd and more physical, giant ants, or more precisely the organisation P.A.N.T.S., whose acronym Green deploys with the same gleeful commitment as SUIT and FISH. The disaster_survival engine makes this the most kinetically intense book of the first four: Mango and Brash are inside a catastrophe rather than investigating one, and the giant insect scale gives Beedie's panel art new opportunities for physical comedy. The science_and_curiosity deep theme (0.5) is new to this instalment, something about the ant biology or the P.A.N.T.S. technology invites questions rather than just laughs. The secondary_genre of science_fiction rather than animals reflects a book that has moved from the animal-detective formula into a new register while keeping all the same players. A strong entry point for readers who want the series at its most chaotic; and the book most likely to prompt children to look up ants.

Why kids love it

The specific delight is giant ants and an acronym worse than the last — Mango and Brash up against P.A.N.T.S., the bug-scale visual chaos some of John Patrick Green's funniest panels yet. The InvestiGators where the series pivots toward sci-fi without losing the bad-pun engine.

  • Becoming invisible
  • Being a detective
  • Having a nemesis
  • Having a secret base
  • Secret world

Why parents love it

The InvestiGators where the series shifts into proper science-fiction silliness — giant ants, a P.A.N.T.S. acronym worse than the last, full-page bug-scale chaos. Reliable for the seven-to-ten reluctant-reader shelf; the kind of book children quote at school for weeks.

About the author & illustrator

John Patrick Green.

JP

John Patrick Green

Writer & illustrator · United States

John Patrick Green is an American author-illustrator best known for the InvestiGators graphic-novel series, a fast, pun-heavy detective comedy starring two alligator agents of S.U.I.T. He also writes and draws the Kitten Construction Company picture books and the Hippopotister graphic novels. Green's style is clean-lined, cartoon-bright and gag-paced, with a strong vocabulary of visual jokes and groan-out-loud wordplay that lands well on read-aloud and gives confident young readers a steady comic engine to chew through. Strong reluctant-reader appeal for ages 6–10, particularly children who already love Dav Pilkey or Aaron Blabey. InvestiGators has been a New York Times bestseller across the run.
