Within Thompson's Oz-era fiction, the character first appears as the Red Jinn in Jack Pumpkinhead of Oz (1929) and is given the name Jinnicky in The Purple Prince of Oz (1932). He is presented as an established magical agent of the Land of Ev, occupying a jar and operating as a resident wizardlike figure who interacts with Oz characters across multiple novels.
Jinnicky's being is housed inside a large red ginger jar (complete with lid) from which his head, arms, and legs are depicted as emerging in fandom and illustrated summaries; texts describe him as speaking in a deep voice. He lives in a red glass palace on the northeastern seacoast of Ev. An early first-edition color plate depicted him with massive piercings, but those piercings are not present in the prose and were omitted from later editions; the pierced depiction is an illustrator's variant rather than a canonical textual detail.
Jinnicky supplies and uses enchanted objects (examples in the novels include the Pirate Sack instruction given to Jack Pumpkinhead, a magic dinner bell, and magic looking-glasses used to find missing persons). He travels by a flying jinrikisha pulled by magic, acts as an ally and patron to characters such as Jack Pumpkinhead, Kabumpo, and King Randy, and maintains attendants (notably Alibabble the Advizier and Addie the Adding Adder). Narrative incidents show him capable of being enchanted and deposed by others, and he functions in the stories as a powerful, recurring magical helper whose artifacts and interventions affect plot events.
