(Y/n), Mordecai and Rigby are playing football in the living room. "(Y/n)! I'm open, I'm open, (Y/n)!" Rigby called to her, and she snickers. "Go long, dude!" She throws a ball of socks at Rigby, sending him backwards off the couch. "Touchdown, sock faces!" He throws down the socks and starts imitating cheering. Right then, Benson enters. "Hey, you three! Quit fooling around; we're having an emergency meeting." He said. "Aw, what?" Mordecai asked.

"Boooo." Rigby whined. "What for, boss?" (Y/n) asked. He signals to the door. "I'll tell you. Outside, now!" He said. He leaves as (Y/n), Mordecai and Rigby watch. Later on all the park workers are standing outside. "Alright, everyone. I got some bad news. The park is being audited." Benson points to Pops. "Pops tried to pay the park taxes..." he gives him a look. "...with lollipops." And (Y/n) snickers. Benson turns to glare at her for a moment before sighing and turning back to everyone. The workers voice their displeasure.

"But I gave them more than enough." Pops said. "We already went over this, Pops. You pay taxes with money, not lollipops." Benson said. "Oh." Pops said dejectedly. "What's the big deal? It's not like an audit is a bad thing." Rigby said. "Rigby, it is a big deal! If we don't take care of this, the government takes our stuff away." (Y/n) said. The rest of the workers panic. "Exactly. Thank you, (Y/n). Okay, we only have till three to stop the audit." Benson said. "Does anyone know someone who can help us? Anybody? Anybody at all?" Benson asked.

Muscle Man raises his hand. "I know someone who can help." He said. "If you say your mom, you're fired." Benson snapped. Muscle Man frowns for a moment, but a goofy smile appears a minute later. "MY MOM!" He said. "GET OUT!" Benson shouted. "It was worth it!" Muscle Man and Hi Five Ghost hi five and run off. "Was it? Now you're jobless." (Y/n) said, and Mordecai and Rigby snickered.

"Hmmm... Hmph. Hey!" Mordecai looks at Rigby. "We know someone." He said playfully. "We do?" Rigby asked him. Mordecai raises his arms. Suddenly, Rigby knows who Mordecai is referring to. "No! No way!" He said stubbornly. "What? If you know somebody, you've got to tell me." Benson urged. "Rigby has a brother." Rigby punches Mordecai. "And he's an accountant." Rigby punches Mordecai rapidly. "Shut up!" Rigby shouted. "Rigby, what's wrong?" (Y/n) asked. "Yeah dude, what do you have against Don?" Mordecai asked. Rigby gets mad, on the verge of crying.

~flashback~

"Guys! Guys! Guys!" Young Rigby said. There are five bored children, one of them a young Mordecai. "Watch me blow out the candles, guys!" A door opens. Rigby's younger brother, Don, stands in the doorway. Somehow, he is taller than Rigby. "Hey, Rigby. Happy birthday, bro." Don said. Rigby gets mad. "Wha? Wha? I told you to stay in the basement!" Rigby snapped.

"Oh. Sorry, Rigby. I just wanted to give you some birthday sugar." Don said. "I don't want your freakin' sugar!" Rigby snapped. "I'll give you some sugar, Don." One of his friends said. "Yeah, me too." Everyone gets up out of their seats to hug Don. Then, Mordecai follows, but Rigby tries to stop him by grabbing his arm. "Don't you dare!" He shouted. "Rigby it's okay, I'm just getting some sugar. Besides, Don is cool." Mordecai goes to Don to give him sugar as everyone else laughs. "You're the best, Don!" Rigby growls.

~present~

"Yeah. Don really made that party." Mordecai said. "Call your brother!" Benson shouted. "No!" Rigby snapped. "Call your brother!" Benson repeated. "No! I hate him!" Rigby shouted, still refusing. "Fine. Mordecai, you call him." Benson said. "You better not!" Rigby shouted. "Rigby, come on! He could save the park!" (Y/n) insisted. "(Y/n), he could ruin my life! If he comes, I'm gonna tell him to leave!" Rigby shouted. Benson walks up to Rigby. "No, you won't! You be nice to your brother or you're FIRED! Call him." He walks off. (Y/n) leans down and pats him gently. "Rigby, just be cool until he stops the audit." She said, he just growls.

Later on the park workers are outside waiting for Don. "You guys are making a big mistake." Rigby said. "Don't ruin this for us, Rigby." Benson said. Don drives up in his convertible. "Really nice car." Benson said. "He looks just like Rigby." Pops said. "Well, they are related." (Y/n) said. Don gets out of his car. "Did somebody order an accountant?" He asked. Everybody laughs except Rigby. "Thank you so much for coming on such short notice. I'm Benson." Benson said. "Give me some sugar." Don hugs Benson. "Nice to meet you. Hey, who's this guy?" Don asked. "I'm Pops." Pops said. "Pops. Give me some sugar." Don said. Pops runs over laughing and gives Don a big hug. "Okay, I honestly think he's going a little bit overboard with the sugar thing, I mean he just met these guys." (Y/n) muttered,

but Rigby heard her and snickered. At least she agreed with him on that... "Don. Good to meet ya." Don hugs Skips next. "Look at this sugar shack. Come here, guy" he gives Mordecai a hug. "I haven't seen you in forever." "Yeah, I know! Oh, it's been forever." He said. "And who's this? Don asked, gesturing to (Y/n). "Oh Uh..." she said nervously. "She's (Y/n). She's another employee." Benson said. Don looks at her for a few moments, making Rigby glare at him. "Nice to meet you, (Y/n). I'm Don, Rigby's brother." He said; "I know." She said. "Care to give me some sugar, (Y/n)?"

Don asked, spreading his arms out. "Uh, um..." she didn't feel very comfortable about hugging someone she barely knew yet, but everyone except for Rigby seemed to be encouraging it. Rigby looks at her and shakes his head threateningly. "Sorry, Rigby." She whispers as she goes to hug him. Rigby looked almost betrayed, then huffs, crossing his arms and turning away. Mordecai chuckles.

"Rigby. Give me some sugar, bro." Don said. "Don't you have taxis to do? Why don't you get to it?" Rigby snapped, and (Y/n) frowns slightly, but Don only chuckles. "Oh. He was always greedy with the sugar." He said. "Augh! I can't wait for you to get out of my life!" Rigby shouted. "What, bro?" Don asked. Benson angrily whispers to Rigby "You keep your mouth shut!" Rigby flinches. "Nothing." He said. Rigby is walking through the hallway as Don and the others can be heard through a doorway in the computer room. "So then I said, "you're not an accountant, you're an account-can't!" Don said. The others laugh at the joke.

"I didn't realize accounting could be so fascinating!" Pops said. "I'm just lucky I get do what I love." He replied. "I'm just lucky I get do what I love." Rigby mocked. Don turns to face him. "Rigbone. Sugar?" He asked. "Shouldn't you be fixing the augite?" Rigby asked. "You mean the audit?" (Y/n) asked. "Don't correct me, (Y/n)! I know what it is!" Rigby shouted. "Whoa, there. I'm sensing some tension, bro. I think it's time we all take a well-deserved break." Don said. The gang - minus Rigby - are outside, and they are playing football. "(Y/n), go long!" He then throws the ball too far. "I got it!" (Y/n) goes to find the ball and sees Rigby already holding it.

A mad expression is evident on his face. "Hello, "(Y/n)". Enjoying your game?" Rigby asked. "Can you just pass the ball please?" Rigby throws the ball hard at her stomach. "Ow! Rigby!" She shouted angrily. "He's not even doing the debit!" Rigby shouted. "It's audit!" (Y/n) sighs. "Rigby, why don't you just try being nice to your brother? He's actually pretty cool." She said. "You don't get it! He..." Rigby began. "Hey (Y/n)! We playing or what?" Don called. "Uh, yeah, coming!" (Y/n) runs off, leaving Rigby looking just as angry as before. Back inside, Don is alone at the computer. "Ah, I just about got this. With a few minutes to spare." Rigby walks in. "Rigbone. How about a little pre-saving the park sugar? You know: for almost being done saving the park?" Don asked. "NO!" Rigby shouted.

"What's going on with us? You never give me some sugar. Did I do something?" Don asked. "Yeah. You were born! And worst of all, you tried to steal (Y/n) from me!" Rigby snapped. "Wow. That's heavy. I gotta get out of here." Don leaves the room. "Dude? No, wait Don!" Mordecai shouted. "I'm sorry. I just... gotta get out of here!" Don said. "Dude, what are you doing? He was almost done!" (Y/n) said furiously. "Ah, he's not so cool." Rigby runs from the hallway to the computer.

"I can finish this up myself." He said. Rigby presses a button on the keyboard. A bunch of ads and warnings appear on the screen as the computer beeps and rattles. OK." He presses another button and more ads pop up. The screen turns red and vibrates dangerously. "Augh! Mordecai! (Y/n)! Help!" He shouted. "I thought you said you could do it!" (Y/n) shouted. "Yeah, dude! What did you do?" Mordecai asked. "I don't know!" Rigby admitted. "This doesn't make any sense." Mordecai said. "No, no, no!" Rigby shouted. Benson knocks on the door. "Don? We brought you a cake. It's almost three. Were you able to stop the audit?" Benson asked. "Uh, almost done, Benson-bone." Rigby said, imitating Don rather badly.

"How do I send this thing?" Rigby asked. "Rigby, call your brother back." (Y/n) said. "No! I hate him!" He snapped. Rigby tries to push send on the keyboard, but Mordecai pushes him away. The two battle on the floor. "Don't... Don't send it! Don't!" Mordecai shouted. "Augh! Must... push... send!" Rigby fights his way up to the keyboard and pushes send. The computer beeps quickly and the clock strikes. It shows a time of 3:05. "Crap!" The trio shouted. "What did you do?!" (Y/n) snapped, glaring at Rigby who flinches. "I... I..." "You are late. Begin audit." The computer shows an 'AUDIT IN PROGRESS' status bar counting up. The computer shakes so much it causes the whole room to vibrate. The clock, lamp, and eventually half the furniture are engulfed in black and white binary code, which causes the items to disappear.

The door also disappears, surprising Benson. The cake and Pops's hat are the next objects affected. "Oh, my..." Pops said. "Where's Don?!" Benson asked. Outside, Don is driving away, almost crying. The others run out after him. "Don! Wait! What happened?" Benson asked. "Rigby blew it!" (Y/n) said. "He wouldn't give Don sugar." Mordecai added. "What?! Go give him some sugar!"  Benson shouted. "NEVER!" Rigby runs away, panting. Inside, Mordecai and Rigby's room is slowly being eaten by the binary code. Mordecai and (Y/n) enter. "Rigby? Rigby!" The two look for Rigby and eventually see his tail poking out from under a pile of clothes on his trampoline.

"Rigby!" "Rigby's not here right now." He said. "Quit being so selfish!" (Y/n) moves clothing out of the way. "The park is disappearing! We have to end this." She said. "Don't tell me what to do! You don't know what it's like to have a brother, so you don't know!" Rigby shouted. "You're right. I don't have a brother. But I kinda know what it's like... 'cause I have you, dude. You're like my brother." Mordecai said. "Really?" Rigby asked, climbing out from under a t-shirt. "Yeah. You're to me like Don is to you. I think you're kinda awkward to look at,

and you embarrass me all the time, and I wish I could trade you in for someone else. But I don't. Because you're like my brother. With brothers you always gotta make do. And I think you should make do, too." Mordecai said, and (Y/n) smiles at that. The binary code continues to eat up the room. "Now will you please get Don to stop this audit?" (Y/n) panicked. Later at Don's house, (Y/n), Mordecai and Rigby are talking to Don, who has answered his front door. "Look, I'm glad you guys stopped by but... I just can't finish the audit. I'm sorry." He said. Don tries to go back inside, but Rigby grabs the door before he can close it.

"Don, please! I need your help with the audit, bro." Rigby said. "Why is it so hard for you to give me sugar?" Don almost cries. "Why do you hate me?" He asked. "He's mad about the birthday party." (Y/n) said. "No! It wasn't just the birthday party. It's everything." He looks up at a photo of Don and Rigby, in which Rigby is literally in Don's shadow. "I'm always in your shadow. You're so much better than me. Everyone likes you better," Rigby almost cries. "And to top it all off, everyone thinks you're my older brother. I'm the older brother! Me! Why do all my friends think you're so much cooler than me?" Rigby asked. Don gasps and slaps his cheeks.

"I... I had no idea. I'm sorry, bro. I didn't mean to steal your friends. I was just trying to be cool like you." He said. "Huh?" Rigby asked. "I've always looked up to you, bro. I get my hair cut like you, I try to look like you, and I don't wear clothes, just like you. Remember when you started walking around naked? I thought you were so cool." Don said. "Yeah, dude. That was pretty cool." Mordecai said. Don looks out the window and sees the park being engulfed by the binary code. "Alright. Let's go save your park." Don, (Y/n), Mordecai, and Rigby drive back to the park, which is being eaten to the point of oblivion by the audit. Inside, they see Pops,

Skips and Benson are hanging from the rapidly-disintegrating house. "Where's the computer?" Don asked. (Y/n) points upstairs. Don runs up and sits at the desk. "Jeez! What did you do, bro?" Don asked. "I tried to do the taxis!" Rigby said. "Hold on. This is gonna be close." Don works on the taxes as the others gather behind him. Sweat forms on his face and he bites his lip. "Alright, I got it! I just have to do one more thing." Don said. "Do it!" (Y/n), Mordecai & Rigby said. Some moments of silence follow and the workers look around. "Why isn't anything happening?" Rigby asked.

"Because..." Don stands up and turns around, arms outstretched. "I still need some sugar, bro." He said. "WHAT?" Rigby asked. "Rigby!" Everyone shouted angrily. Rigby jumps through space on the scattered household items to his brother, who catches him. A few minutes later everyone is outside, and the house and park back to normal. "Aw, Don. Do you have to leave already?" Mordecai asked. "Sorry, Mordo, but an accountant's work is never done." He said. "Thanks for everything, Don." Benson said. "Do come back soon!" Pops said. "Mmhmm." Skips said. "Well, big brother, if you ever need some sugar, you know who to call." Rigby smiles, and Don gets in his car. "Later, gators." Don drives off. (Y/n) leans in to Rigby with a giant smirk. "Sugar?" She teased playfully. "Shut up!" Rigby snapped.
