InvestiGators
by John Patrick Green · InvestiGators #1
Two alligator spies, toilet-based travel, and more puns than you can shake a tail at
The story
Mango and Brash are the InvestiGators — alligator agents of S.U.I.T. who travel through the sewers and use Very Exciting Spy Technology to solve crimes. When a famous chef goes missing, these two mismatched partners must work together on their first case, navigating baking disasters, exploding science labs, and a mystery that turns out to be bigger than either of them expected.
Age verdict
Best for ages six to nine. The humor and visual format make it accessible to early readers while the mystery plot keeps older kids engaged through about age ten or eleven.
Our take
A kid magnet that parents tolerate — pure entertainment with exceptional gateway power and creative spark but limited educational depth
What stands out
Each audience's top 3 dimensions. Out of 30 scored per book.
Kids love
- First-chapter grab Strong
Comparable to Lunch Lady and the Cyborg Substitute — opens in grounded kid-space (spy agency HQ) with immediate visual hook (mustache gag) and character voice contrast. Sits below Artemis Fowl because the opening lacks the criminal-mastermind stakes, but matches Lunch Lady's accessible entry point perfectly.
- Middle momentum Strong
Off the Hook — the dual-crime structure (Gustavo + Science Factory) prevents middle sagging through constant beat changes every 2-3 pages. Multiple overlapping mysteries escalate in waves. Sits at this level not below because momentum is relentless, but below 5 Worlds (which adds three parallel protagonist threads) because InvestiGators uses serial mystery revelation rather than true parallel narratives.
Parents love
- Reading gateway Strong
Comparable to A Bear Called Paddington — the full-color graphic novel format, constant humor, minimal text per page, and high-interest spy-adventure concept lower every barrier for reluctant readers. Present at Scholastic Book Fairs and featured on multiple reading lists. Below 5 Worlds because that book has added media-franchise saturation; InvestiGators relies on peer-cultural status.
- Creative spark Strong
Comparable to Interrupting Chicken — includes a how-to-draw tutorial that directly invites kids to create their own characters and comics. The spy agency concept inspires pretend play, gadget design, and creative writing. The accessible art style empowers kids to imitate and create rather than just consume. Below InvestiGators: Off the Hook because Book 1 has slightly less absurdist mashup material.
Teachers love
- Reluctant reader rescue Strong
Comparable to Babymouse #20 — a top-tier reluctant reader rescue alongside Dog Man and Captain Underpants. The graphic novel format, constant humor, visual engagement, minimal text per page, and high-interest spy premise eliminate every barrier between a resistant reader and a completed book. Present at Book Fairs with massive cultural recognition. At this level rather than Dog Man because Dog Man has more slapstick visual comedy; InvestiGators relies more on wordplay.
- Writing prompt potential Strong
Comparable to A Tale Dark and Grimm — rich prompt options include designing a spy agency, creating gadgets, writing news reports about story events, crafting villain origin stories, creating original comic mysteries. The graphic novel format especially inspires visual-writing hybrid projects that engage reluctant writers. Below Blended because that book has more identity/perspective-scaffolding built into the narrative; InvestiGators requires teacher mediation.
✓ Perfect for
- • Kids who love Dog Man
- • Captain Underpants
- • or Bad Guys — graphic novel readers who want a mystery with nonstop laughs and clever wordplay. Also great for reluctant readers who need a visual
- • funny
- • fast-paced entry point into independent reading.
Not ideal for
Readers looking for literary depth, real-world educational content, or sustained emotional weight — this is pure entertainment with a light emotional thread.

Mood & style
You'll know it worked when…
Extremely high completion rate. Short graphic novel format, constant humor, and visual engagement mean kids who start this will almost certainly finish it, often in a single sitting.
