When Moo hears about Minnie's missing snack, she believes it to be the beginning of a crime wave and convinces Minnie to go undercover. A clue leads them to the hen house, where both Elvis the rooster and a marauding fox jump to conclusions about the disguised cows. The humor is in the candy-colored illustrations and the duo's straightforward delivery of absurd assumptions.

Gr 1-3-Cazet offers another strong entry in this beginning chapter-book series about two lovable cows. Minnie believes her jelly donut has been stolen and Moo is determined to catch the thief.

The cheerful illustrations depict the action and contain details that are sure to elicit even more laughs.
