Plot

Pulp Heroes, the DCU Annuals event, continues with a story in the spirit of the adventure magazines of the 1930s. A cryptic message from Rex Leech leads Superboy and Roxy to a mysterious island where dinosaurs run free, Rex runs the natives, and Superboy gets to run around in a loincloth when he crowns himself 'King of the Jungle' and fights a giant white gorilla.
