Willy was the hot dog vendor on Sesame Street, appearing sporadically between the 1970s and the early 1990s.
Willy served mostly as a background character, interacting with the cast minimally from time to time. He appeared, unnamed, as early as Episode 0131 with his first known named appearance in Episode 0406. He also appeared in Follow That Bird amongst the street residents.
- Willy wears a yellow feather in his hat, a possible reference to Big Bird. Kermit Love built the original Big Bird Muppet.
- In Episode 0250, Gordon refers to him as Mark Anthony. However, the two share a laugh about it, suggesting it's merely a gag nickname.
