As Sonic, Tails and Knuckles were approaching Station Square in the Tornado, they could notice a bunch of Eggman's robots causing mayhem on the streets of Station Square.
"Wow, Eggman's robots sure are causing a ruckus down there." Tails said, noticing the robots.
"He sure is. Knux, let's get down there and start trashing those robots!" Sonic said to Knuckles.
"You know it, Sonic! Let's do this!" Knuckles said as he jumped off the Tornado and began gliding down to Station Square.
"Okay, I'll regroup with you guys once I have landed the Tornado." Tails said to Sonic.
"Alright, catch you later, buddy!" Sonic said, giving a thumbs up to Tails before jumping off the Tornado and skydiving down to the streets of Station Square. Knuckles landed on the streets first and Sonic followed shortly after. A bunch of E-2000 robots were firing laser projectiles at the citizens of Station Square.
"E-2000s? This is gonna be a bit tough..." Knuckles commented upon seeing the E-2000s.
"Well, we can still take them! Let's give it our best shot, Knuckles!" Sonic said as the E-2000s turned to him and Knuckles. Sonic and Knuckles began attacking the robots, but they held up their shields so they couldn't be damaged. Knuckles grabbed onto the shield of one of the E-2000s and judo flipped him over, allowing Sonic to destroy it.
"Maybe we should try this teamwork move on these guys." Sonic commented, with Knuckles nodding in agreement. They then began combating the other E-2000s with the same move. Knuckles judo flipped the E-2000s over and Sonic Homing Attacked them a few times to destroy them. A bunch of citizens were filming the battle between Sonic, Knuckles and the Eggbots on their phones, but the Station Square police force drove them back.
"Get to safety! Don't film this fight on your phones, no matter how cool it may look!" A police officer told the crowd.
An E-2000 managed to grab onto Sonic, but Sonic kicked it off him by kicking it in the head. Knuckles punched some E-2000s whenever he could find an opening. The two of them were soon joined by Tails, who assisted Sonic and Knuckles in combat with a laser blaster. He fired it at the E-2000s whenever there was an opening. Once enough E-2000s were destroyed, the trio found a moment to catch their breath.
"Hey, Tails. Glad you got here, buddy." Sonic said, giving Tails a fistbump.
"Glad I could help, Sonic." Tails replied.
"I don't think that's the last of them. There's more Eggbots coming our way!" Knuckles said, pointing at a bunch of Cop Speeders flying their way.
"Let's get rid of them any way we can!" Sonic said, raising the morale of both Tails and Knuckles. The trio engaged the Cop Speeders in combat.
Meanwhile, at the Station Square Museum...
The Chaotix had arrived at the museum and walked up to the front desk.
"Excuse us, we're here because we were requested by the Station Square Mayor to investigate the theft of a sapphire that is in your possession." Vector told the receptionist.
"Hold on for one moment." The receptionist said as she called the manager of the museum. "Sir, the Chaotix Detective Agency has arrived." She told the manager over the phone. "...Alright, I'll send them in." The receptionist hung up the phone. "The manager is in his office. Go up the stairs to the second floor and then head up more stairs to get to the manager's office." She told the Chaotix.
"Alright, thank you, ma'am." Espio politely said to the receptionist as he, Vector, Charmy and Mighty entered the museum and went up to the manager's office. Vector knocked on the door.
"Come in!" The manager called. The Chaotix entered the office.
"Hello, sir. We're here just as the mayor requested." Vector said to the manager.
"Very well. Close the door and have a seat." The manager said as Vector shut the door and the Chaotix sat down in a set of four chairs that were in front of the manager's desk.
"So, a sapphire was stolen from your museum, correct?" Mighty asked the manager.
"Yes, a sapphire was indeed stolen from our museum." The manager replied. "It was stolen over night, while the museum was closed. A night guard heard the shattering of glass and when he approached the source of the noise, he noticed that the sapphire was gone." He explained.
"Was there any evidence left behind?" Mighty asked again.
"The thief left behind a note saying that they want a sum of 150.000 Rings in exchange for the sapphire, or they will destroy the sapphire." The manager told Mighty.
Mighty nodded. "Did the thief leave a name on the note?" Espio asked.
The manager shook his head. "No, they did not. They only said that they wanted a sum of 150.000 Rings delivered to the Mystic Ruins." He explained.
"150.000 Rings? That's quite a lot of money..." Charmy said as he scratched his chin.
"It is. But do you think you can figure out who the thief is and return the sapphire to the museum?" The manager asked the Chaotix.
"We will do our very best to track down the culprit and return that sapphire, sir. You have my word." Vector told the manager.
"I'm very glad to hear that. I look forward to the sapphire's safe return." The manager said.
Vector nodded and turned to Espio, Charmy and Mighty. "Well, let's go, boys! We got a case to take care of!" He said. Espio, Charmy and Mighty nodded.
"The first thing we're gonna need is the note that was left behind so we can figure out a culprit from the handwriting." Espio said to the manager.
"Of course. We collected the note and put it in a Ziploc bag that we put in the safe behind me." The manager said as he opened the office safe and got the Ziploc bag with the note in it. He then handed it to Espio.
"Thank you." Espio said as he got the note out of the Ziploc bag and began to inspect it. "Let us see here..." Espio mumbled as he inspected the note.
In the next part, the Chaotix might be able to get a lead in their case and the battle against the attacking Eggbots continues.
