Big Bird and Mr. Snuffleupagus see that the snow on the sidewalk has been shoveled, and it has frozen over with ice, so they decide it would be fun to slide on it. Big Bird goes first, but when Snuffy tries, he falls shaking the street with him. Big Bird can't get him back up by himself, so he recruits the help of some kids. With much pushing and pulling, Snuffy is back on his feet again. When he tries to slide a second time, he falls again. Big Bird suggests he just try sliding on his tummy - it would be easier for everyone. A girl wonders what would happen if she popped her balloon. She imagines it would scare her sister, who would end up breaking a vase and getting in trouble. (thetvdb.com)
