Yolanda calls Jenny "the Green Lama". The Green Lama was another comic book character who was introduced in 1940, the same year that Alan Scott first appeared as Green Lantern.
Alan Scott's Green Lantern has a very different origin story from the later Hal Jordan's. Scott was the first lantern and he first appeared in All-American Comics #16 (July 1940), published by All-American Publications. He was a railroad engineer who came into possession of a Green Lantern that spoke to him and gave him powers. From this, he created the Green Lantern's ring. The original comic book was canceled in 1949. The character was brought back in 1959 as Hal Jordan, but he had a new name and origin story. This character was completely different than the Green Lantern character of the 1940s. He received his ring from a dying alien and was commissioned as an officer of the Green Lantern Corps, an interstellar law enforcement agency overseen by the Guardians of the Universe. It is obvious Stargirl is using the first Green Lantern so he ring can be passed down.
