George has to take a pile of stuff down to the recycling center. He comes upon Steve who is holding Betsy's wagon. He has a package for Betsy that he is picking up from the package delivery right next door to the Recycling Center. George places all of his stuff in the wagon but, after an accident, one of the wagon's wheels pops off and Steve later winds up sending it rolling off on its own. With the wheel lost, Steve and George must find a new one that is the same size as all the others because, if one is used of the wrong size, the wagon does not travel straight.
