Shadow looked around, as they walked inside the cave. "When do we find this chaos emerald, this is taking forever!" Knuckles exclaimed. Shadow rolled his eyes.

"Be quiet, we just got here," He replied. Knuckles nodded.

"Whatever Shadow," Knuckles said. Shadow continued to walk deeper and deeper into the cave until they came across a bright chaos emerald.

"There it is, get it," Shadow demanded. Knuckles hesitated then stopped.

"Wait a minute, you just want me to get hurt by the trap," Knuckles said, as he foled his arms.

"What trap?" Shadow asked.

"There's always a trap. The emerald wouldn't be standing here like that," Knuckles rolled his eyes. Shadow frowned.

"Knuckles, just get the emerald and stop being so afraid," Shadow said. Knuckles growled.

"Who are you calling afraid?!" Knuckles asked angrily.

"Then why won't you get the emerald then if you are not afraid, Knuckles?" Shadow asked. Knuckles gulped and glared at Shadow.

"Because..." Knuckles whispered.

"Because what?" Shadow asked curiously.

"Because...I'm...I'm...." Knuckles said quietly.

"Because what, spit it out already," Shadow demanded.

"Because I'm not afraid of anything!" Knuckles exclaimed and grabbed the emerald. Suddenly the ground opened up from up under Knuckles. "WHOA!!!" Knuckles exclaims and fell into the hole. Shadow tried to grab at him but missed. "Curse you Shadow the Hedgehog!" Knuckles shouted, as he fell into the darkness.

Shadow sighed and folded his arms. "The fool had to get into trouble," He mumbled coldly. Shadow sighed again then jumped into the hole.

When Knuckles made it to the ground it looked like "Lost World" from Sonic Adventure DX. Knuckles looked around. "Whoa..." He said in awe. "This place is amazing, but of course, I've been here before," Knuckles got up and started walking with the emerald in his hand. Suddenly the music from that stage, "Lost World" started to play.

Shadow landed where Knuckles had landed and looked around. "Darn, where is that echidna?" Shadow asked, as he started walking.

Knuckles suddenly started going down a water slide. "Whoa! Hahahaha!" Knuckles laughed, as he slid down.

Shadow heard some rushing water and followed the sound.

Knuckles's laughter stopped because he fell into some deep water.

Shadow didn't see the rushing water and slipped and fell into the water. "What the....ahhhhhh!"

Knuckles swam to the surface and looked around. Suddenly he dropped the chaos emerald. "Oh no!" He exclaimed.

Shadow was about to fall into the deep water but something hit his head and it was the chaos emerald. Shadow passed out and sunk down, down to the bottom.

Knuckles swam down and saw Shadow and the chaos emerald but there was this huge stone snake (From Sonic Adventure DX) coming right at the emerald and Shadow. "Oh...which one? The emerald or Shadow? I'm picking the emerald!" Knuckles swam for the emerald.

Shadow was unconcious now.

Knuckles grabbed the emerald then looked at Shadow. The snake was almost there to him. Knuckles rolled his eyes. I gotta save him. Knuckles thought and swam for Shadow.

Shadow was waking up. He opened his eyes and saw the snake heading straight his way. The snake was inches away from him then suddenly, Knuckles pulled Shadow up to the surface. Shadow was coughing. "You okay Shadow?" Knuckles asked.

"Yeah, I'm fine," He replied. "Something hit me in the head," Shadow rubbed his head in pain. Knuckles thought about the chaos emerald.

"Well...it must have been a rock or something," Knuckles told him. Shadow nodded slowly.

"I suppose," Shadow said.

"Now come on, that snake is going to come back," Knuckles told him. Shadow nodded and they swam to shore. After that they saw three doors. "Which one do we take?" Knuckles asked.

"We'll just have to find out," Shadow answered and went to the door in the middle. He opened it and he and Knuckles walked in.

Knuckles opened his eyes and they were in the "Crazy Gadget" stage from Sonic Adventure 2 Battles. "What the...." Knuckles said, as he looked around.

"Come on! We have to get moving!" Shadow demanded, as some G.U.N robots started shooting at them.

Shadow and Knuckles stopped at the last part of the stage and looked around. "What is this?!" Shadow asked. Knuckles saw a rocket and the goal. The goal was inside some box thing and you had to press some button for the rocket to hit the box that the goal's in.

"Over there," Knuckles pointed at the goal. Shadow looked and nodded.

"Let's go," Shadow said.

Ten hours later...

"I can't find a way over there!" Knuckles exclaimed. He was standing on the red platform. Shadow growled and folded his arms, he was standing on the blue platform.

"I'll just use chaos control," He said. Knuckles looked at Shadow.

"You made us waste all this time and you could have chaos controlled us over there?" Knuckles asked. Shadow didn't say anything and held up the chaos emerald.

"Chaos control!" He exclaimed but didn't go anywhere. "It looks like it doesn't work in here," Shadow said. Knuckles sighed.

"Then how do we reach that goal?" He asked. Shadow smiled.

"I have a plan..."

A couple of minutes later...

"You're so heavy!" Knuckles exclaimed, as he glided towards the goal.

"Stop complaining and glide faster!" Shadow shouted. Shadow was on Knuckles's back, standing up.

When Knuckles made it there he collasped onto the ground. Shadow walked over to the rocket and pressed the button. The rocket broke the box the goal was in. Shadow smiled. "Let's go," Shadow dragged Knuckles into the goal.

They appeared in front of the doors again but this time there was only two. "Which one do we go in this time?" Knuckles asked.

"That one!" Shadow pulled Knuckles into the door on the left.

They suddenly appeared in the stage, "Meteor Herd" from Sonic Adventure 2 Battles. "Where are we?" Shadow asked, as he looks around.

"I've been here before, maybe we have to look for all of the pieces of the master emerald," Knuckles told him.

"The master emerald is shattered?" Shadow asked.

"No! I mean we just have to look for them in order to get out of this stage," Knuckles replied.

"Alright then, you look, treasure hunter," Shadow demanded with his arms folded. Knuckles glared at him and went to go look for the pieces.
