Hey Foster's fans! I just wanna make a quick note about this first chapter/start of the story - I wrote this chap kinda as a one-off thing like over a year ago and didn't think I was really gonna continue it, but recently I've decided I wanna carry on with it and have written 2 more chapters... now, I wanna point out that the standard of this chapter is pretty low compared to the other two, & i am gonna improve this one, but i just wanna say pleaseee read on 'cus it does get much better and Chapter One doesn't lay out the standard of what the whole story's gonna be like (: thankyouuu!

Ooo another point! I know Mac is meant to be about 8 years old in the series, but in this story I kinda see things as a bit more grown-up and realistic so I've moved the time frame about 5 years… so Mac is about 13 ½ whilst this is all happening :) enjoy!

DISCLAIMER: I do not own Foster's.

All had been going well in the Foster's house - Mac, Bloo, Eduardo, Wilt + Coco had just sat down to play a board game in one of the bedrooms upstairs, and everyone had been feeling pretty alright for the past ten minutes. But all of a sudden, Mac didn't feel alright at all. His stomach had started to churn and he was beginning to feel pretty sick. He didn't know whether he was gonna puke or burp or something, and he had a familiar feeling about this indistinction - it was just like how he'd felt the last time he'd ate nuts.

"Mac? You don't look so good."

Mac didn't feel like talking either. He was worried he'd definitely be sick if he tried to talk. Mac glanced in the mirror across the room. Even his face was tinged slightly green.

He felt his stomach starting to boil up, going all bubbly.

"Urp!" he said, clasping his hand over his mouth. He knew what was coming next. Quickly he got off the floor and dashed out of the room.

"Mac! Where are you going?" Bloo was right behind him. He didn't know that Mac was heading to the bathroom and he didn't know how awful he felt.

It was too late. Mac puked all over the red carpet on the landing. Bloo was commenting in disgusting, saying things like "Ew!" and "Gross!" and then he ran back to the bedroom to tell the others.

Mac felt rather woozy. He tried not to step in the vomit. But then he felt another load coming up again and dashed to the bathroom.

He managed to barf into the toilet this time, but then he felt really weak and collapsed on the floor.

Mac woke up to see Wilt hanging over his head.

"Mac? Are you okay, buddy?" He asked him, looking concerned.

He felt totally washed out, and he betted that he looked terrible.

"Yeah…" he whispered weakly. Mac tried to sit up but then he felt an awful twang of pain in his stomach. He winced.

"Ooh!" said Wilt, "Try and lie back down, Mac. You musn't move much if your stomach hurts. I'm really sorry to say this but I think you've got a bad stomach bug."

Obviously the others had found Mac and put him in a bed in their room.

"No." He said, his voice a bit wispy, as he eased himself back down. "I think it was those peanuts in the cake last night. I think I'm allergic to nuts."

"Cocoocooo – cocococococococo!" Coco pointed out.

"No, they shouldn't have put peanuts in the cake." Mac said, "But they didn't know I was allergic."

He looked around the room. It was only Wilt and Coco.

"Where's Bloo and Eduardo?" He asked weakly. Mac was starting to feel a bit pukey again. Luckily there was a bucket beside his bed, he assumed Wilt had put it there.

"Well…" Wilt looked a bit nervous. "Bloo's downstairs, eating lunch. I'm sure he'll come up to see how you are in a minute or so."

"Cocococoocoocoocococo." Coco stated, and Mac figured that she was the one telling the truth.

Apparently Bloo wasn't really downstairs, he was hiding because he thought Mac had caught a dreaded virus and he definitely didn't want to catch it. How selfish could he be? Mac was meant to be his best friend yet he still didn't want to see him and wish him well.

Mac suddenly felt the peanuts rising again. He grabbed the bucket and had a long barf into it, much longer than the two sicks he'd performed before. He really hoped it was his last barf. When he lifted his head out of the bucket he saw that Wilt and Coco were grimacing at him. But Mac was sure they understood.

"Don't worry. I'll be better soon. The last time I ate peanuts I was only sick for a day." He said shakily.

"Well, I'm sure you'll get better soon, then, buddy." Wilt said, being really re-assuring and smiling. He took the puked-in bucket from the side of Mac's bed, and trying not to look inside, he went out of the room to wash it out.

Wilt went into the bathroom to throw the barf down the toilet. Unfortunately Frankie was cleaning the sink and caught a whiff of the chuck.

"Eww- what's that smell, Wilt? I think you might've been eating too many peanuts."

"No, Frankie. Mac's been sick. He was sick twice last night as well - he says it's because of the peanuts. He's allergic to them." Wilt explained.

"Aww, poor Mac." Frankie said, looking sympathetic. "I hope he gets better soon. When did he eat peanuts?"

"Well, he said they were in the fudge cake last night, but he didn't realize. Neither did Mr Herriman know that Mac was allergic to peanuts."

Frankie suddenly looked a bit puzzled. "Mr Herriman never did put peanuts in the cake last night…"
