The Ancient Musical Seashell!

Dennis: "Do you think we're really gonna find that ancient musical seashell here?" Dennis: "That horn sound is coming from the cave over there. That must be the marsoulous cave, and that horn must be coming from the 18,000-year-old seashell in that study" All right! Everything's fine. Now, there's a fur cloak for you, Dennis. Ooh! And a fur suit for you, Guy Rosie. Well, what are we waiting for? Time to step out into the stonage.
