InvestiGators

Alligator agents Mango and Brash use Very Exciting Spy Technology and toilet-based sewer travel on their first mission together, where two mysteries demand simultaneous clue work. The absurd equipment and puns sit inside a recognizable detective structure: go undercover, gather evidence, and keep both cases from escaping.

This suits a reader who wants a full-color graphic mystery with brisk action and an established team. The volume introduces the partnership and the agency’s rules, so it is a cleaner entry than a sequel. Nate the Great offers one quiet missing-object case and an explicit reasoning chain; InvestiGators is broader, faster, and more gadget-driven.
