The Adventures of Nicki and Ricky: The Case of the Duck's Teeth (Paperback) (ISBN-13: 9798989075447)

A local museum trip inspires the sleuths to seek the living relatives of a specimen so strange they thought it had to be extinct! Detectives Nicki and Ricky are convinced that the prehistoric-looking duck is a dinosaur, but the docent (who happens to be their grandfather) says it's not extinct. Time to search outside! Sibs Nicki and Ricky use naturalist skills and the Socratic Method to find out more about the "dino duck" in the third graphic novel of the Baffling Birds trilogy.
