Birdy Pox

The Birdy Pox is a disease Big Bird contracted in Episode 3434 of Sesame Street. First, the infectee gets green polka-dots on their feet, then the legs, then the back, the chest, the tummy, the face, the wings and finally the tail. The cure for it is rest for a day, which is odd as fatigue is not a symptom. It only affects bird Big Bird's species and only if they are six years old. Telly Monster tried telling the spots to go away, Big Bird tried sleeping and Count von Count tried counting the spots to make them go away. Neither of it worked, but they always go away at night.
