Which one of the following Muppets has noticeable synophrys?

BiologyOnline.com's dictionary defines synophrys as a "medical term for hypertrichosis in between the eyebrows, thus giving an appearance of a single long eyebrow".

It is the presence of abundant hair between the eyebrows so they seem to join together to form one long eyebrow, also known as a unibrow.

Former President George W. Bush, basketball player Anthony Davis, Mexican artist Frida Kahlo, and Bert from "Sesame Street" are just a few notable people who have sported the monobrow. Bert initially appeared on "Sesame Street" in 1969, with his signature spiky hair and epic unibrow. His best friend and roommate, Ernie, interestingly, has no eyebrows.
