InvestiGators: Take the Plunge
by John Patrick Green · InvestiGators #2
Spy alligators go underground — literally — in a sewer-surfing sequel packed with puns and surprisingly deep questions
The story
Secret agent alligators Mango and Brash are sent into the city sewers when their headquarters comes under attack and a dangerous piece of technology goes missing. As they navigate underground dangers and track a familiar villain, a parallel subplot about robot emotions and a mind-bending invention raises questions about identity that are smarter than they first appear. Think spy thriller meets bathroom humor meets philosophy for kids.
Age verdict
Best for ages six to nine where the humor hits hardest, though the series' philosophical moments about identity and consciousness keep older elementary readers engaged beyond the slapstick.
Our take
A kid magnet with exceptional gateway power — pure spy-comedy entertainment lifted by surprisingly philosophical undertones about identity and consciousness
What stands out
Each audience's top 3 dimensions. Out of 30 scored per book.
Kids love
- First-chapter grab Exceptional
Comparable to Lunch Lady and the Cyborg Substitute — Opens with in-media-res spy action at rocket base, goofy character humor, full-color visual engagement. Sits at/above because the immediate combination of sophisticated setup (spy mission) + absurd humor (goofy disguise, Mango enthusiasm) creates stronger dual appeal than Lunch Lady cafeteria simplicity. Operatic opening exceeds grounded setting. Evidence: depth_1 opening_hook shows immediate competence + comedy with zero friction.
- Laugh-out-loud Exceptional
The Scarlet Shedder — Joke density matches best comedy graphic novels: every 2-3 pages. Wordplay (COMBINOTRON codes, puns), physical comedy (Prime Robot infinite hugging loop), absurdist humor (robot emotions), situational irony (bathroom emergency during mission). Toilet humor appropriate for age 6-10. Sits below Dog Man because Dog Man layers 5+ humor channels; this book layers 4 effectively. 9 reflects graphic-novel excellence.
Parents love
- Reading gateway Strong
Comparable to 5 Worlds , triangulated with A Bear Called Paddington — Premier gateway book for reluctant readers. Full-color graphic novel, constant humor, minimal text per page, high-interest spy-adventure concept. Present at Scholastic Book Fairs, part of #1 NYT bestselling series with massive elementary recognition + cultural presence. Sits at 5 Worlds adjacent because both are apex gateway formats. 8 is solid.
- Creative spark Strong
Off the Hook , triangulated with Lunch Lady — COMBINOTRON concept directly fuels imaginative play (kids invent combinations). Spy agency inspires pretend play + gadget design. Accessible art style + series drawing tutorials empower kids to create own comics. High-interest invention engine. Sits at Lunch Lady level because gadget spark is similar; slightly below Off the Hook because less established series tradition in Book 2. 8 captures creative fuel.
Teachers love
- Reluctant reader rescue Strong
The Scarlet Shedder , triangulated with Babymouse — Top-tier reluctant reader rescue alongside Dog Man + Captain Underpants. Graphic novel format, constant humor, visual engagement, minimal text per page, high-interest spy premise eliminate every barrier. Present at Book Fairs with massive cultural recognition among elementary readers resistant to traditional chapter books. Sits at Babymouse/Dog Man level. 8 recognizes tier-leading potential.
- Writing prompt potential Solid
design original spy gadgets, create combination stories, write villain origin stories, craft news reports about events. Graphic novel format especially inspires visual-writing hybrid projects engaging reluctant writers through comic creation. Sits above Bake Sale because spy-gadget design + villain backstory exceed food-business prompts. Below Tale Dark because fewer craft-imitation opportunities. 6 solid.

You'll know it worked when…
Extremely high completion likelihood — the visual format, constant humor, and spy-mystery momentum make this nearly impossible to abandon once opened. Even the most reading-resistant children tend to finish in one or two sittings.
