This puzzle was drawn by Matthew Inman of The Oatmeal. Its based on his dog, Rambo.

The thought bubbles over Rambos head show what he dreams about while hes napping. On the left are his nightmares -- vacuum cleaners and bathtubs, and on the right are his dreams -- squirrels wrapped in bacon and infinite tennis balls. This puzzle tells a dozen tiny stories about what we love about mans best friend. Its a good puzzle for people who like small victories -- because each section of the puzzle tells a tiny story.
