S04:E51 - Fill'er Up Scotty // the Niagara Falls Mystery // Helpers' Helper

Busytown comes to a stop when Scotty Dog runs out of gas and the tanker truck breaks down on the highway. // Cucumber and Pickles are on a photo shoot at Niagra Falls when the falls dry up. // Deputy Flo and Sergeant Murphy are usually the ones to help people in Busytown.
