His character evolved from a recurring Green Anything Muppet dashiki-wearing hippie (who was usually seen alongside other Anything Muppet hippies) from season 1 and season 2 that (naturally with Anything Muppets) was often interchanged (for example, while the character usually was Green and had moppy red hair, some skits portrayed him with different hairstyles and AM patterns, including a skit where Grover talks about the word "exit," where the character was seen with frizzy black hair instead of his usual red hair (First: Episode 0210), and another skit where the character was portrayed as a Lavender Anything Muppet while spelling out the word "run." (First: Episode 0226)) By the time his band name appeared on the second Sesame Street cast album, Little Jerry had become an established character.
By the late 1980s, his original hippie garb had been exchanged for a white and black leather jacket and a chain necklace. In the band's comeback appearance in 2000, he also sports a pair of sunglasses.
Little Jerry is considered to be male, but in one Shalom Sesame sketch, in which an actress dubbed the character for "Proud," host Mandy Patinkin introduced the rocker as female: "Little Jeri (sic) is loud and proud, and why shouldn't she be?."
Little Jerry was named after his performer Jerry Nelson, who later talked about the character and his group in a 2009 interview:
Before the character had been established, the initial recurring nameless Green hippie puppet had other performers, including Frank Oz in the original "Before and After" segment, and Fran Brill in a season 2 sketch with Grover where a group of Anything Muppet hippies (unenthusiastically) spells out the word "WALK."
- A Jim Henson character resembling Little Jerry who played drums (and sang lead) appeared in a cover of "Spinning Wheel" during Sesame Street's first season.
- Little Jerry's mother and brother are referenced in Episode 2452 when he describes about feeling mad when returning home.
