AJ, Spike, and Rainbow Dash went through a long cave, and after a while, they emerged in a giant cavern. In the center, there was a tall pillar with a staircase going up to it. It was surrounded by water with unevenly placed stones forming a bridge. At the top of the pillar, there was a beam of light. Rainbow Dash pointed at the pillar, and said "It's right up there!" AJ nodded, looked at Spike, and said "Wait here." As AJ began to cross the bridge, Spike said "Oh." He pouted, and looked behind him. "Huh?" He said as he was staring at a shrine with a golden dragon. The outstretched claws held a giant emerald, and Spike was hypnotically drawn to it. On the other side of the cavern, AJ reached the end of the bridge, and started climbing the stairs. Rainbow Dash was watching AJ, but she turned around to see Spike walking towards the giant emerald. She began to panic as AJ reached the top of the pillar. As Rainbow Dash tried to pull Spike away from the giant emerald, AJ began to examine the prize he was looking for. It was a statue of creature with a head of a pony, a deer antler on the right, a blue goat horn on the left, one long fang, a snake tounge, a goat beard, white bushy eyebrows, a right arm of a lion, a left claw of an eagle, a right leg of a lizard, a left leg of a goat, a bat's right wing, a pegasus' left wing, a horse's mane, and a dragon-like snake's tail with a white tail tuft.

"This is it?" AJ said looking at the statue questioningly. "This is what we came all the way down to-." He stopped when he saw Spike pulling away from Rainbow Dash to grab the giant emerald. When Rainbow Dash let Spike go, AJ said "SPIKE! NO!" But it was too late. Spike grabbed the giant emerald, and a booming voice which belonged to Ahuizotl said "INFIDELS!" Spike flinched, and said "Uh-oh!" As Rainbow Dash said "Oh My Gosh! Spike, what have you done?!", AJ gulped, and Ahuizotl said "YOU HAVE TOUCHED THE FORBIDDEN TREASURE!" The cavern began to shake as Spike gently placed the giant emerald back on the golden dragon shrine, but they both melted into lava. "NOW YOU WILL NEVER AGAIN SEE THE LIGHT OF DAY!!" Ahuizotl said as AJ grabbed the statue which shrunk just enough to fit into his back, before the light on the pillar turned into fire, and ran down the steps. Spike ran on the bridge, making Rainbow Dash spin like crazy. AJ raced down the stairs, but they flattened into a slide. He slid down until he flew into the air. He screamed while he was about to fall into the water that turned into lava, but Rainbow Dash was quick enough to catch him with her cloud. Spike tried to run on the bridge, but the rocks exploded on both sides, leaving him trapped on one of the rocks. "Help! Help! Help!" Spike called out as Rainbow Dash and AJ raced over, and the rocks behind and front of Spike exploded. Before the last rock that Spike was standing on exploded, AJ grabbed him, and said "Gotcha!"

They looked behind them to see a tidal wave of lava coming towards them as AJ said "Whoa! Rainbow Dash, let's move!" "You got it, AJ!" Rainbow Dash as she pushed her cloud towards the cavern exit. Together, they raced back through the caves, dodging walls, and falling debris. After they dodged a giant falling boulder, Spike grabbed AJ's head, and covered his eyes. "Spike! S-Spike, this is no time to panic!" AJ said as he pulled Spike off of him. He gasped when he saw that they were flying into a wall, and said "Start panicking!" "Hang on!" Rainbow Dash said as they went into a dive as AJ and Spike screamed. They entered the treasure room, and lava poured on to the gold, silver, and jewels causing them to go up in flames. The fire formed into hooves, and tried to catch AJ, Spike, and Rainbow Dash, but they escaped the flames. Outside the cave, Ahuizotl growled and roared in pain as the wind blew very hard against Cranky Doodle Donkey who was waiting for his prize. Inside the cave, the stairs crumbled away, and AJ, Spike, and Rainbow Dash tried to make it to the top, but a boulder crashed on Rainbow Dash's tail, knocking AJ and Spike off the cloud. Spike climbed out, but AJ wasn't so lucky because he was hanging on a step, and Rainbow Dash landed on the ground with a boulder crushing her tail.

AJ tried to climb up, but he slipped, and almost fell. "Help me out!" AJ called out. "Throw me the statue!" Cranky Doodle said. "Ah can't hold on!" AJ said. "Give me your hoof!" "First give me the statue!" Cranky Doodle said. AJ reached into his bag, and took out the statue. He reached out, and gave it to Cranky Doodle Donkey who laughed, and said "YES! AT LAST!" He laughed, and placed the statue in his bag. Spike tried to pull AJ up, but Cranky Doodle Donkey kicked him aside, and grabbed AJ's hoof. "What are ya'll doing?!" AJ asked as he struggled against Cranky Doodle Donkey. "Giving you your reward!" Cranky Doodle said in a crazy tone. He pulled out a crooked dagger, and in Princess Luna's voice said "Your ETERNAL REWARD!" Before he had a chance to stab AJ, Spike stopped him, and bit him in the hoof. Cranky Doodle Donkey screamed, and dropped AJ. He glared at Spike, and threw him into the cave. They screamed as they fell, but then Rainbow Dash quickly pulled her tail out of the giant boulder, and caught them with her cloud. Some rocks fell on them, and knocked them out. Ahuizotl roared, and the entrance to the cave collapsed. the sphere rose from the ground, splitted in two, and fell to the floor.

Princess Luna chuckled cruelly, took off her disguise, and said "It's mine! It's ALL MINE!" She reached into her bag for the statue, but to her confusion it wasn't in her bag. "Where is it?! No!" Princess Luna asked. She then dropped to her knees, and said "NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!" Meanwhile in the castle in Canterlot, Shining Armor was standing in the doorway to Applejack's room. "Applejack?" Shining Armor called out. Applejack was sitting on her bed with Fluttershy sitting next to her. "Dearest? What's wrong?" Shining Armor asked. Applejack sniffled, looked at her father, and said "Princess Luna...has...done something...terrible!" "There, there, there, my dear." Shining Armor said. "We'll set it right." Shining Armor sat on the bed with Applejack and Fluttershy, and said "Now, tell me everything." Applejack took a deep breath, and proceeded to tell her father everything that happened in Ponyville.
