In today's episode, the kids in Explorers' Troop 301 once again find themselves in trouble on the surface of an alien planet, as the giant Saphrite sends out an army to stop the invaders. And once again, the explorers have to head beneath the surface of a planet before they can blast off. But! What does it mean when you head below the surface of a living planet? It means some…interesting…terrain. SPOILER ALERT: DON'T READ THIS BEFORE LISTENING TO THE EPISODE: Today's episode ends with a riddle. Here is the text of it. If listeners know the answer, email [email protected], and we'll relay it to the explorers. We'll also send out a prize to everyone who submits a correct (or reasonable) answer: Around you I spin but disappear Whenever you see gold I’ve been around for millions of years But I’m only a month old. Send us your answers!
