Cover ArtI like this collection because it has A LOT of comics in it. I like the series overall because Hobbes as the imaginary friend makes me nostalgic for when I was a super-little kid even though I myself didn't have an imaginary friend (I'm still a kid, but I'm not super-little any more). Also, Calvin is super bad, and that's really funny. I laugh out loud every time I read this. If you like this one, you should also read The Indispensable Calvin and Hobbes and, for a shorter one, Attack of the Deranged Mutant Killer Monster Snow Goons.
 
Publisher description:
Beginning with the day Hobbes sprang into Calvin's tuna fish trap, the first two Calvin and Hobbes collections, Calvin and Hobbes and Something Under The Bed Is Drooling, are brought together in this treasury. Including black-and-white dailies and color Sundays, The Essential Calvin and Hobbes also features an original full-color 16-page story.
