After spending the weekend talking with David Wiesner at the Kutztown Children's Literature Conference, I developed a deeper appreciation for his new book Mr. Wuffles. This picturebook has a different illustration pallet that many of his other books. The colors are bolder and brighter. The story revolves around a curmudgeonly cat that finds a toy to play with only it is actually a spaceship full of aliens. The aliens hide in the walls of the house, only to realize that mice have been drawing on the walls inside the walls like the art in the Caves of Lasceaux. Wiesner uses four different types of speech bubbles to alert the reader to whom is talking. I will have to revisit this one for sure to see what I missed in my first few readings.
