Dr. Flippin

Dr. Flipper is a seal doctor who appears in a season 21 episode of Sesame Street (later repeated as a season 23 episode). Despite his profession, his facial hair makes him resemble a walrus.

Telly is left to watch Wolfgang the Seal while Bob runs downtown. Wolfgang soon becomes unwell, so Telly calls Dr. Flipper, Wolfgang's doctor. Dr. Flipper gives Wolfgang a check-up and concludes he's merely depressed, not sick. Wolfgang's condition improves when Bob returns, happy to see him.
