Series: The Drill House | Episode 5 of 5

At the bottom of the cave system, three ancient lava beasts guard the Power Diamond — and they are not interested in negotiating. Avery and Quinn reach the volcanic chamber and find the diamond sitting on a rock column above rivers of active lava, protected by armored creatures that have been guarding it for centuries. Avery's sword works on ice mode. Fire mode does not work at all. Quinn's force blasts help, a triceratops they rescued along the way helps more, and Biscuit the pocket panda contributes exactly one sneeze at exactly the right moment. Getting the diamond out before the volcano responds is a different problem entirely. The biggest, most action-packed episode yet — a fantasy audio adventure for kids ages 6-11, perfect for car rides.
