The Yellow Peri makes her final pre-Crisis appearance in Action 567 (May 1985), in a story by Rozakis, Schaffenberger and Hunt..
With her husband Alvin, Loretta, the Yellow Peri, has opened a housing development protected from the vagaries of the climate by her magic, and Lois and Clark come out to investigate.
Peri uses her magic to create rapidly harvestable food, but as they eat it, they discover that it makes people speak the truth. It begins as Clark reveals that he is Superman. Revelations spiral, until Loretta hears Alvin admit that he never loved her, and married her on a dare. When Superman and Lois wind up preparing to wed, Peri gets jealous, and things go crazy.
The story is clearly written for comedy. And I do enjoy the bit when Superman tries to get rid of the book, but can’t. Loretta no longer wants it, but Superman finds it cannot be destroyed. He seals it in lead, which causes all its effects to vanish, for some reason.
The end of the story teases the return of the book, and therefore, the Yellow Peri, but Crisis wiped all that out.
She does appear again, though not for a very long time, making her next appearance in the miniseries 52.
