Pokemon Mystery Dungeon Red

Charmander decides shut his cryhole. "Hey, how's about we call Nucertes and see what's going on here?" Pikachu looks at him and says, "What the fuck are you talking about? Nucertes? Hmm... Oh, you mean Prometheus?" And Charmander was all like, "Who's Prometheus?" And then Pikachu goes, "You know, that Marowak that helped us beat M?"

What should Charmander do next?
