Clovis Crawfish returns for an exciting new adventure in the bayou country. In this escapade, Clovis and his fellow bayou creatures must deal with a strange and unwelcome visitor.

Michelle Mantis is a frightful-looking old insect, called "Cheval de Diable" (Devil's Horse) by the other critters. She has a ravenous appetite and even threatens some of Clovis's friends! The heroic crawfish dissuades her, however, and Michelle turns her attention to a colony of ants instead.

When Michelle accidentally tumbles into the mud, too full to move and unable to fly with muddy wings, she becomes trapped. Although the other bayou denizens are reluctant to help Michelle, Clovis convinces them that they cannot leave her stuck in the mud, no matter how much they are afraid of her. Freed by the efforts of Clovis and his friends, Michelle is grateful for their help and sorry for all the trouble she has caused.

With its lively illustrations, in color as well as black and white, this book is certain to appeal to children ages five through eight. Two earlier volumes in the series, Clovis Crawfish and Petit Papillon and Clovis Crawfish and His Friends, won the Printing Industries of America Graphic Arts Award in 1985 and 1986 respectively.
