Under the light of a silvery moon, an inquisitive bear ventures into People Town, where he makes quite the curious discovery. What is this? A springy thing-a bouncy thing-a sit-on-it, jump-on-it thing! This Thingity-Jig is way too heavy to bring back to the woods by himself, however, so Bear runs home to tell his friends. But nobody wants to get out of bed to help! So Bear invents a Rolly-Rumpity to wheel the Thingity-Jig home, and then it all gets stuck in the mud. How will Bear tackle this bump in the road? With a Lifty-Uppity, of course!
