S2E9 Ghost Beach

Jerry is eager to venture into the eerie, shadowy cave he discovered near the beach. However, the other kids share a chilling tale that gives him pause. They speak of a ghost residing deep within the cave, a spectral figure that's been around for three hundred years. This ghost supposedly emerges during the full moon, haunting the shoreline. It’s just another silly ghost story, isn’t it?
