A part of Milton Bradley's "T.H.I.N.G.S." series, players try to roll barrels across the bridge while Go-Rilla raises and lowers it. From the box: Can your roll the barrels to safety before time runs out? Push the explorer's button. A barrel will roll out of his backpack and onto the rocking, rattling bridge. Keep pushing the button to roll out the barrels. Will they roll safely into the cabin - or get knocked off the bridge? When the timer stops Go-Rilla pops the bridge open! How many barrels made it into the cabin?
