Under the light of a silvery moon, Bear wanders into people town and discovers a springy thing, a bouncy thing--a sit-on-it, jump-on-it thing! This Thingity-Jig is too heavy to carry home by himself, so Bear runs back to the woods and asks for help. Too bad for Bear, his friends are sleepy and shoo him away. So Bear invents a Rolly-Rumpity to wheel the Thingity-Jig home, but then it all gets stuck in the mud! How will Bear tackle this bump in the road? With a Lifty-Uppity, of course!
