"Tickle Time!" is the twelfth in Boynton's astoundingly successful "Boynton on Board" series. Based on the wildly popular song from Boynton's wildly popular "Rhinoceros Tap" CD, "Tickle Time!" is pure irrepressible Boynton, lively in tempo, nimble in rhyme, and filled with irresistible fuzzy cats that cavort from page to page. Plus a few birds, who aren't the cavorting type. Here's a book to turn to again and again, because it's guaranteed to elicit giggles: If you're feeling blue and you don't know what to do there is nothing like a "Tickle Time" to make you feel like new. Whether you tickle high or tickle low, tickle fast or tickle slow, it's the gitchy-gitchy-goo that makes everything worthwhile.
