The lyrics to S'Winter are here below. Phineas: It's S'Winter. Adyson, Gretchen, and Isabella: Well, there's snow on the ground, There's sleigh bells all around, But the sun's beating down 'Cause it's S'Winter, It's ski and snowball-fight time, And also fly-a-kite time, Cold and sunny, Yes, that's right, I'm talking about S'Winter. It's a S'Winter s'wonderland, Unusual and grand, You can freeze while you get tanned, Because it's S'Winter, Talkin' about S'Winter, It's so S'Winter. Phineas: Some people call it "Wummer."
