Alvin and the Chipmunks

Mind Over Matterhorn (3x19)

: 16, 1985

While the Chipmunks are on tour in Switzerland, Brittany is depressed about the Chipettes’ relative lack of fame. So Alvin arranges for the ultimate Swiss publicity stunt: the gang will climb the Matterhorn and the Chipettes will give a concert at the mountain’s peak. But they soon become trapped in an avalanche.
