Mrs. Hatchett, the school librarian, has discovered that Kim has a very overdue book, and must work in "library lock-up". Ron realizes that he had borrowed it without asking just before a mission, and lost it at some villain's lair. While Kim is working in the library, Ron and Wade (via a remote-controlled robot) visit various villain's lairs looking for the missing book, foiling their current world domination plans at the same time. At the final one - Monkey Fist's - Ron's backpack is spilled revealing that he'd had the book all the time. Ron returns to Middleton, and puts the book back, getting Kim out of detention.
Did You Know?

What's up, Kim?
Have you heard from Ron? I haven't seen him all day.

AH, AH! IT'S GOT ME! OH MAN, IT'S GOT ME...!
Ron? Uh... haven't heard a peep.
With my mutagenic plants, I shall build a new world! A world that I control!
OW! THORNS! OH, THEY HURT WHEN THEY'RE POKING! OW!
