Mr. Wuffles! by David Wiesner

Mr. Wuffles is a finicky cat who is dissatisfied with all of his toys except one, which actually happens to not be a toy at all. Instead, it's a teeny little spaceship manned by a group of itty bitty alien visitors. When their ship is damaged by Mr. Wuffles, the aliens set forth to fix it and come across a civilization of bugs that also know the villainy of Mr. Wuffles.

Leave it to David Wiesner to mix bugs, aliens and cats together to make up a good, quirky children's book. The illustrations are funny and vivid, and his choice to include different kinds of speech for the species in the book was neat: aliens speak in symbols, the bugs speak in scratches, etc. Kids who like to come up with their own stories or who like for adults to make up stories for them will enjoy this book. Very creative!
