Gary's Synthesizer

At Skips' house, (Y/n), Mordecai and Rigby are cleaning out his garage while he's on the phone. "Sorry Gary, I can't. I'm cleaning out my garage today." Gary and the Guardians of Eternal Youth are traveling the galaxy in Gary's El Camino. "But we haven't had a guy's night out in ages and we're passing right through your galaxy." Gary said. "I told you, I can't go!" Mordecai grabs a hat rack and notices something. "Whoa! (Y/n), Rigby get over here." He said. "Let me guess, immortal  junk... Whoa." They are looking at a synthesizer. "Dude, that's the coolest thing I've ever seen." (Y/n) said. Rigby walks up to it, mesmerized. "So cool." He said. "No, dude! Look!" (Y/n) points to the sign that says "Do not touch" Rigby scoffs. "How many times does touching stuff we're not supposed to caused a problem?" He asked.

"Like every time, dude." (Y/n) crosses her arms. "Well, maybe this time nothing will happen. Watch." Rigby cranks up the volume. "Cool." Mordecai and Rigby said. "Guys, I really don't think we should be-" (Y/n) began. Rigby pulls out a plug, which causes a small surge as the synthesizer vibrates. "Nice. Hmm."

Rigby puts the plug in a different outlet. "Yes yes yes!" Mordecai said. They both giggle as they start mixing the plugs around, and (Y/n) grabs Rigby's right arm. "Boys, stop it!" She scolded. Skips enters the garage. "What are you doing!? That's Gary's synthesizer!" A crash is heard. The four of them look outside to find the Guardians of Eternal Youth dazed as they exit Gary's El Camino, which crashed into a tree. "Are you guys okay?" (Y/n), Mordecai, Rigby and Skips head over to them. "We're fine." Reginald said.

"Where's Gary?" Skips asked. "Well," there's a flashback to when they were traveling. "We were on our way to the galactic mall..." "Come on, Skips." Gary said. "...when Gary straight up disappeared." Gary disappears, causing the Guardians to gasp. Boswold grabs the steering wheel. "I don't know how to drive the stick." They all scream as the car swerves. "Only one thing could've caused this.

Reginald said. "Which one of you messed with his synthesizer?" Boswold asked, and Skips and (Y/n) glare at Mordecai and Rigby. "Uh, messed with?" Rigby asked. "I mean, we might've unplugged some cables." Mordecai said. "Fools! That device synthesizes Gary's physical being into existence." Reginald scolded. "So, Gary's dead?" (Y/n) asked worriedly. "No! His consciousness still resides within the snyth. But, until you put the cables back to make the correct patch, the device won't project his physical form." Reginald said.

"It's cool. We'll just put it back the way it was. How hard can it be?" Rigby asked. Everyone is gathered at Gary's synthesizer. "Skips?" Mordecai asked. "Oh, no no. Can't help you here. Just plug back the cables you unplugged." Skips said. "Right."  Mordecai said nervously. "Piece of cake." Rigby said. The two of them plug the cables into random spots. "Hm, hm, hm, hm, hm!" The duo said. Rigby presses a key, which causes the synthesizer to emit a loud high frequency sound. This culminates in Skips' windows and his glass harmonica shatters. "My priceless glass harmonica!" Skips shouted. (Y/n),

Skips and the Eternal Youth Guardians glare at Mordecai and Rigby. "Any sign of Gary? No?" Rigby asked. "Why would Gary leave such an important thing in Skips' garage?" Mordecai asked. "Hmm... good question. You'd think with something as important as this he'd want to keep it hidden or something..." (Y/n) mused. "That's it! You must travel to Gary's home world of Synthos to recreate the synth patch to bring him back!" Reginald said. "Wait, what?" Reginald snaps his fingers, transporting (Y/n), Mordecai, Rigby, Skips, and Gary's synthesizer to Synthos. "Aah!"  Mordecai and Rigby shouted. At Synthos, the four of them and the synthesizer, which Mordecai and Rigby are carrying, arrive. "Whoa." (Y/n), Mordecai and Rigby said.

David and two of his guards appear. "Welcome, new arrivals, to Synth City. I'm David, King and Ruler of Synthos." He said. " 'Sup? I'm Rigby. I'm the King of Earth." (Y/n) hits him with the synthesizer. "Oh! Ow." He said. "Welcome, Earth ambassadors. I trust you can..." David looks at Skips and gasps. "Oh! Hey!" He points to Skips, then himself. "Bare chest, bare chest. Twins." David poses as one of his guards takes a photo of him and Skips. "That one's going in the album. Will you be with us for long?" He asked. "No, we unplugged a patch on this thing and we just need help re-synthesizing our friend." Mordecai said.
