Shark vs. Train
Chris Barton, illus. by Tom Lichtenheld (Little, Brown)
This is one of those elementally brilliant ideas that evokes a "Why didn't I think of that?" response. By pitting a cartoon train and shark against each other in a series of increasingly ludicrous challenges (the train's heft is a liability in a hot air balloon race, but very effective on a seesaw), Barton and Lichtenheld tap into kids' innate ability to turn anything, anything into a competition.
