This is segmented into short parts labeled in Roman Numerals...

I: Words
Sensei: "Long ago, types were four … just ... one more." Hat Pop: "A fourth element? Another Knight?" Seahorse: "Long ago, Knights were three, but now, ye search near the tree." Sensei: "Well said, Seahorse." Ben: "The Community Garden?" Hat Pop: "Yes, maps up. Click the mine."

II: Tree
Penguin: "Fire, ye burn this tree! Water, ye feed it. Snow, ye burden it, ye make it cold." Ben: "Whaaa?" Penguin: "Forth type, he gives you soil, tree." Seahorse: "Soil? Could it be?"
 * Ben picks up a glowing brown card. Power 10, type... a rock?

Ben: "A rock?" Hat Pop: "The Lost Card." Seahorse: "The Lost Card? The Legend of Crag's Berg Card?" Hat Pop: "No, the Herbert's Tunnel card." Ben: "EARTH!!"
