The swat bots put up thier guns, ready to fire at the four Hedgehogs. "Freeze," said one of the swat bots. "Those four are under arrest." Everyone was a bit confused. Why would the swat bots be aresting thier own guys. People thought that Sonic was also one of them. "Go!" shouted Nights. Nights was starting the treasure hunt. Everyone went all over the casino. Metal Sonic and Silver Sonic curled into balls and used multiple homing attacks. They easily defeated the swat bots. "Okay guys," said Sonic. "We have to find that gray emerald before anyone else does." Sonic noticed a bat girl sneaking inot a purple booth. When she went into the booth, she was sucked up top. "Look!" said Sonic. "That bat girl was sucked up in that booth. She looked like she knew what she was doing. Let's follow her before this anry mob kills us." "Wait," said Silver Sonic. "There's another booth over there. And it's blue." "Yeah," said Shadow. "Okay, me and Metal Sonic will go in the purple booth, you guys go in the blue one. We can't let that bat girl get that emerald." The four split up. When they got sucked up, they found themselves in a giant pinball game. Shadow and Metal Sonic were in NIGHTS Pinball. Sonic and Silver Sonic were in SONIC Pinball. They all heard a strange voice on a laodspeaker. Nice job. Lets see if you can collect five hundred rings. If you do, I will let you go to a non-accecable place in this casino. And at the end, you will find the Emerald. GO!" Shadow and Metal Sonic curled into balls and used themselves as pinballs. Shadow noticed that bat girl flying into a passage. Shadow couln't get there. He had to clear the pinball game. Metal Sonic however, could fly. He tried to fly out into the passage but he would keep getting caught by Nights. In the other pinball machine, Sonic and SilverSonic were doing great. But they knew if they fell out, they would lose. Metal Sonic and Shadow finally collected five hundred rings, and the pinball game stopped. "Well done," said Nights. "Now let's see if you can make it to that emerald." "Silver Sonic and Sonic also finished. They were transported to the NIGHTS Pinball game. THey were standing next to Sadow and Metal Sonic. "Now let's see if you can get to that Emerald," said Nights. The floor under Sonic and Shadow opened and they fell into the sewers under the casino. "Sorry," said Nights to Metal and Silver. "No robots." Metal Sonic and Silver Sonic were sucked out of the pinball game and into the casino. Sonic and Shadow were in the sewer. "EWW GROSS!" said Sonic. "We gotta go through this smelly shit?" "Well we better hurry before that bat girl finds the Emerald." said Shadow. Sonic and Shadow raced through the sewers. Meanwhile, back in the casino, Metal Sonic and Silver Sonic were in the middle of a mob war in the casino. People were going crazy searching for the emerald. "That's it!" said Metal Sonic. "Everyone!" he yelled. "Get out of the casino right now before we call reinforcements to imprison you all and turn you into robots!" Everyone paused and then ran out of the casino like there was no tomorrow. "Hehehe," said Metal Sonic." "Nice work," siad Silver Sonic. "Now we gotta get to that. I have a feeling that bat girl will get there before Sonic and Shadow do." "I say we look for them in that vent." said Metal Sonic. "Fine," said Silver Sonic. The vent was closed, so Silver Sonic curled inot a ball and bashed it open. Metal Sonic and Silver Sonic flew inside. They just fit in. It was dark, so they lit up thier eyes to see. Suddenly, they heard a growl. "What was that?" asked Metal Sonic. Meanwile, in the sewer, Sonic and Shadow went crazy. They couldn'tget through it. There were swat bots even in the sewrs of the city! They finally reached a dead end. "What do we do now?? asked Sonic. Suddenly a huge pipe sucked them up. It pulled them to a huge opening. The room was huge. In the middle of the room, they saw the Chaos Emerald floating. "Alright," said Shadow. "We found it." Sonic and Shadow ran towards the emrald, when that bat girl came from behind them. "I don't think so," said the bat. "Hey who do you think you are?" asked Sonic. "Well last time I checked my name was Rouge the treasure hunter." "Well we need that emerald," said Shadow. "The outcome of the war may depend on it." "War?" replied Rouge. "We are hardly at war. The Eggamn Empire controls us. We can't make any attmepts to resist." "Well," said Sonic. "We could resist if we have the seven Chaos Emralds." Just then, one of the walls broke open. A huge orange lizard came out roaring. "AHHHHHH!" screamed Rouge. "The Biolizard!' said Shadow. "It's one of the other research projects created to withstand radiation." Metal Sonic and Silver Sonic came chasing into the room. "Just let us use the Chaos Emerald" said Sonci to Rouge. "Never!" said Rouge. She then grabbed theEmerald and flew away. "Great!" said Sonic. "There's no place to go! We're gonna have to make a fight of it."
