Paw Patrol - Season 3 Episode 30 -

Mayor Humdinger drops off a 'gift' to Mayor Goodway, a flower that spreads a horrible stink when it blooms. Mayor Goodway tries to return it to him, but runs into trouble and has to be rescued by the PAW Patrol. It takes Ryder, the pups, and Rocky's brand new tugboat to get that stinky plant out of Adventure Bay before it explodes stink seeds everywhere.
