The ninth episode of the second season of Dennis the Menace (1986), and the seventy-fourth episode of the series overall.
Menaced Marriage
Dennis reluctantly accompanies his folks to Mr. Wilson's niece's wedding and causes various mischief. First, he brings Willy, his pet frog, who causes a panic to the guests and to Margaret, who's the flower girl at the wedding. He then swallows the wedding ring. Ruff also manages to arrive and tears up the bride's dress. Despite the hitches, the wedding is a success and Alice is sure the bride and groom's marriage will only get better once they leave Dennis behind.
Dennis of the Yukon
Henry's company sends him on an assignment in the Yukon to conduct tests at a secret radar installation. He takes Ruff with him since his new collar has secret codes for the tests. Dennis sneaks on the plane and Henry reluctantly takes him along for the mission, but when they arrive at the facility, a spy posing as a fur trader named Jacques LaBrouche has raided it, then makes off with the dogsled, including Ruff as the lead dog. Dennis pursues LaBrouche to his cabin, only to get captured and tied up by the villain. After freeing himself, the boy and Ruff chase LaBrouche, eventually winding up at a dogsled race, then are able to stop him cold when they get him into a bobsled run—without a bobsled—leading to his arrest by the Mounties. Dennis and Ruff are made honorary Mounties themselves and proudly wear their uniforms on the plane ride home.
Seal of Approval
Barko the seal is on his way to Ocean World, but slides out of his transport van and joins in the fun as Dennis, Gina, and Jay are playing baseball. Afterwards, Dennis takes him home, but eventually, he sneaks off to Mr. Wilson's house where he eats his catch of the day, then plays around as the kids try to corral him. Mr. Wilson's house is messed up, but the kids manage to get Barko outside where the van's driver finally finds him. As a reward, Dennis stars along with the seal in Ocean World's feature show, as his mother is shocked to see him on TV.
