Mr. Snuffleupagus (Sesame Street)

According to Muppet Wiki, "Mr. Snuffleupagus is Big Bird's best friend who lives with his family in a cave, just off to Sesame Street. His full name is Aloysius Snuffleupagus although Big Bird and his friends call him Snuffy. His sister is Alice. His famous quote is "Oh, dear..." He often calls Big Bird "Bird." He first appeared on Sesame Street in Season 3 (1971-72). When he appeared, Big Bird's adult friends thought he was his imaginary friend. Until in Season 17 (1985-86), he was finally seen by all of Big Bird's adult friends. His favorite foods are cabbages and spaghetti."
