Mighty World River Explorer

One of many adventure kits from Mighty World, the River Explorer set comes with two character figurines and a load of other accessories to stimulate kids' imaginations. The bright yellow, heavy-duty truck and trailer both have free-rolling wheels and are accompanied by a raft, boating and camping gear, and an alligator.
― “Our rack is empty right now, so they've been doing good,” Wallace Harvey, manager of Three Cheeky Monkeys in Los Angeles, Calif., told TDmonthly of Mighty World, which he listed as his best-selling playset during an April 2010 survey.
