After all the Olympian gods go missing, Sibyl has a premonition in which the sun god Apollo tells her to find "the talking pig". Sibyl then sets out looking for the talking pig, Gryllus. She finds him first at an auction where she buys him for 200 drachmas then Gryllus runs away and he winds up at Big Stavros's Kebab bar where he is forced to entertain customers and where Sibyl takes him back. Together they set off for the temple at Delphi. Apollo informs Sibyl that she and Gryllus must find a goatherd boy living on top of a mountain. Once Sibyl and Gryllus find the goatherd, (who turns out to be the god Zeus) they set off once more for Apollo's temple at Delphi. It is there that Gryllus, the talking pig, must save the world from utter destruction.
