It all starts with a flea. When it lands on a scruffy dog, it initiates a series of encounters that lead to mad adventures. The flea bite causes the dog to jump wildly and land on a man. They both go flying into a mud hole and get caught in a rainstorm. When they get the remedy to stop the itch, the flea jumps to a cat and the next round of mayhem ensues. Told almost entirely in a simple aabb rhyme scheme, the book adds interest and enthusiasm via onomatopoeia and mild expletives executed in large, bold upper-case letters. They “Squish-squash” in the mud, and the dog’s tail goes “whump-whump” as the man cries “gadzooks” and “egads.” Although rhyming “flea” with “immediately” is more than tortuous, most of the rhymes are of the one-syllable variety and are nicely accessible for young readers. Lester’s computer-enhanced pencil-and-watercolor cartoons are highly exaggerated and filled with movement. Readers’ eyes will be drawn to the immediate action, but there are also lots of details they might notice on a second perusal. A puzzled rabbit sits in the grass, a couple of birds laugh hysterically at the muddy twosome and a snail and frog also watch the antics. Clever fun and lots of giggles. (Picture book. 3-5)
