Something Under the Bed Is Drooling (ISBN 0836218256) is the second Calvin and Hobbes printed collection. The book was released in April 1988 by Andrews & McMeel and collects the strips published from August 18, 1986 to May 22, 1987. The included Sunday strips were reprinted in color in The Essential Calvin and Hobbes and The Complete Calvin and Hobbes. The title of the book comes from a single sunday strip in which Calvin tricks the monsters under his bed into drooling hungrily, thus revealing them. This comic is the first one featured in the book.
