Dave's most despised teacher, a gleeful frog dissector named Ms. Veronica Krockle, is absent. Her students are psyched! But Sticky is suspicious. Especially when the substitute teacher turns out to be strangely interested in geckos. Or rather, boys with pet geckos.
Thats no substitute! Thats Damien Black, dastardly treasure hunter and master of disguise!
If Damien Black is in school, does that mean he's behind Ms. Krockles absence? Could she have been kidnapped? And does that mean Dave has to rescue her? Ay chihuahua! The caped crusader is (reluctantly) on the case.
