In this chapter, Phineas and Ferb are going to fight Knightbrace. You know, the villain that embodies the nightmares that children have about going to the dentist? If you've ever had a fear of going to the dentist, you likely don't want to meet this guy.

Of course, since Phineas and Ferb aren't afraid of visiting the dentist, maybe they'll be fine. Besides, they've fought against a mummy before, so why can't they fight against a dentist? Alternatively they could try looking for Frankenstein's brain, though it's probably anywhere in the world by now.

Chapter 8: Brace Yourself

As they started brushing their teeth after eating so much candy, Phineas and Ferb began to notice that someone was outside. Phineas decided to investigate. It could be a member of the KND who was trying to get them something...but it could also be an adult that was an enemy of the KND.

Unfortunately, it was the latter...though at least it wasn't Count Spankula this time. They probably wouldn't have to worry about him for a whle. It was a good thing really since they weren't looking forward to being spanked, the poor kids.

He looked like some sort of ninja...but since when did ninjas ever have braces? It was quite unusual, to say the very least. Of course, some of the members of the Kids Next Door's rogues gallery did dress rather strangely, such as the Toiletnator for example.

Not only that, but he seemed to be hurling globs of toothpaste at their treehouse. It was rather peculiar...not to mention messy. They might have to clean up the treehouse later.

Currently, he was snickering to himself. Unfortunately for them, they were being visited by Knightbrace, an evil ninja who used to be a man by the name of Mr. Jelly who worked at a candy store.

It was rather ironic...but he had gotten kicked out of dental school for trying to put braces on babies, so he couldn't get a job as a dentist. Where else was he to go? Work at a garbage dump?

"I heard that these kids beat Count Spankula...that does seem rather concerning. Meh, I'm sure that I'll be fine. Maybe they just got lucky." remarked Knightbrace to himself. Besides, he wasn't allergic to garlic.

It looked like Sector P had been called into action once again...even if they hadn't received orders from the Kids Next Door Moon Base.

"What's going on out there?" asked Phineas. For some strange reason he got the feeling that he was up to no good. He did look rather menacing...though at the same time he also looked rather goofy.

"Well, since there's apparently there's an adult that has a craving for candy at the expense of children, it seems reasonable that there would be a villainous dentist as well." noted Ferb.

"If that's the case, we better get ready." answered the boy. If he was trying to break into the treehouse, he was most likely trying to give them a rather nasty dental session.

Normally they wouldn't mind going to the dentist that much, but this dentist was an EVIL dentist. He most likely had a sadistic streak. Having a dental appointment with him certainly wouldn't be fun.

Immediately, Phineas sounded the alarm. They were going to have to fight evil once again.

Isabella, Buford, and Baljeet showed up a few seconds later. Apparently, their treehouse was once again under attack by the forces of darkness...or should we say the forces of adults?

"What's the matter?" asked Baljeet.

"We're under attack by a dentist!" exclaimed Phineas.

"A dentist?" questioned Isabella. What were the chances of that? Then again, there were a lot of kids that were afraid of visiting the dentist, regardless of whether the dentist was crazy or not.

At that very moment, Knightbrace broke down the door, laughing as he did so.

"Maybe we should make that door more durable." suggested Isabella. Having a door that WASN'T durable was looking for trouble when you were a member of the Kids Next Door.

"Yes. Yes, we should." nodded Phineas.

"Yes! I'm in!" exclaimed Knightbrace. Now all he needed to do was find the KND agents inside so that he could give them a good brushing at their expense.

"He'll be here soon...and I don't think that he has a dentist license. Get your weapons!" warned the leader of Sector P.

"I'm on it!" shouted Isabella.

"You can count on me!" bellowed Baljeet.

"We can take this clown on!" exclaimed Buford, cracking his knuckles. After all, they had accomplished things that other kids would only be able to dream about...apart from other members of the Kids Next Door, that is.

Immediately, the five children began to arm themselves. They couldn't exactly take on an adult with their bare hands, now could they? On the other hand, Isabella did know some grappling techniques.

Eventually, they were all ready to fight adult tyranny...from within their own treehouse.

Sure enough, Knightbrace climbed up the stairs, a wide smile forming on his lips as he spotted Sector P. He was going to enjoy this.

"There you are! I noticed that you've been eating a lot of candy! It's time for a dentist appointment!" exclaimed Knightbrace.

"It's true, we have been eating a lot of candy lately." noted Phineas.

Of course, they had all armed themselves...but he was sure that he would win regardless. He had weapons too...and lots of them.

"Maybe we would accept if you weren't a sadist!" bellowed Buford.

Knightbrace started by arming himself with drills, and slowly walking towards the five. Apparently he was trying to look menacing.

"You cannot escape! Don't even try!" exclaimed Knightbrace. Where was the emergency exit when the Kids Next Door needed it?

With Baljeet, it was succeeding. Already he was feeling scared...and the fight was only beginning.

"I'm scared." remarked Baljeet, sweat coming down his face. First a vampire, and now an evil dentist? What exactly WAS the world coming to?

"Hold yourself together!" ordered Buford. If they panicked, it would be all the more easier for Knightbrace to beat them.

"It's time for me to give you a root canal! Ready?" shouted the ninja.

"I'd be ready if your idea of a root canal wasn't painful. Everyone open fire!" answered Phineas.

In retaliation, he began to open fire on Knightbrace along with his teammates.

Immediately, Knightbrace was pelted with gumballs. He quickly shielded himself using a rather large toothbrush so that he didn't get hit by too many of them.

"Ergh! Using candy to attack me? Typical." answered Knightbrace. It was like children using orange juice to fight back against the Common Cold. However, he built the Flu Bug Machine to make orange juice less efficient.

In retaliation, he tossed a toothbrush at Phineas.

"Yikes!" exclaimed Phineas.

Fortunately, Ferb pushed Phineas out of the way so that it didn't hit him.

"Darn it! I missed!" bellowed Knightbrace. Maybe he needed to work on his aim a bit more.

"Thanks, Ferb! I knew that I could count on you!" exclaimed Phineas. He was glad that he was his stepbrother.

"Of course you can! He's your teammate!" shouted Isabella.

In fact, so was she.

"Why don't you have some toothpaste?" asked Knightbrace, pulling out a big tube full of toothpaste. The tube full of toothpaste in question had a skull on it and was colored black. This was not the toothpaste that one should use before they go to bed.

"He's pulling out more weapons!" warned Phineas.

"How many does he have?" questioned Baljeet. Each of them had only picked out one weapon to fight Knightbrace with...and yet Knightbrace had brought a large supply of them.

Well, it seemed smart that he would prepare himself before entering the Kids Next Door treehouse...it was five against one.

Immediately, he pelted Buford with the toothpaste.

"Aah! I'm hit!" exclaimed Buford. There was a large glob of toothpaste on his shirt now.

"Gotcha!" shouted Knightbrace.

"You alright, Buford?" asked Baljeet, wiping the toothpaste off of his partner.

"I think so." nodded the bully.

Knightbrace then pulled out some dental floss and attempted to grab one of the five.

"Let's see whose first on my appointment list, shall we?" asked Knightbrace.

He grabbed Baljeet.

"Aah!" exclaimed Baljeet.

"Yes, come over here so that you can experience my high-power drills!" bellowed Knightbrace.

"Not the drills!" shouted the young boy.

However, as Baljeet was being pulled towards the evil dentist, Buford grabbed onto him. He wasn't going to let Knightbrace take his partner that easily.

"Oh no, you don't!" bellowed Buford.

Quickly, he began to pull Baljeet away from the crazed dentist so that nothing bad happened to him.

"C'mon, c'mon!" exclaimed Knightbrace. Buford was really strong for a kid his age. There was a reason why he was effective at bullying others...though he didn't bully people very much ever since he had become friends with Phineas, Ferb, Isabella, and Baljeet.

Finally, Buford broke the dental floss and dragged Baljeet away from Knightbrace.

"Thanks." said Baljeet. He was worried for a second that he was in for a terrible experience.

"Curse you!" bellowed Knightbrace.

In retaliation for bullying his friend, Buford punched Knightbrace in the face as hard as he could.

"Ow!" exclaimed the ninja.

"That's for trying to give Baljeet since a nasty dentist appointment!" bellowed Buford.

However, since Knightbrace was bigger, he was able to kick Buford backwards.

"Oof!" exclaimed the bully.

Immediately, he crashed into the bathroom.

"Buford's really taking a beating, isn't he?" questioned Phineas.

"We might need to take him to the Kids Next Door infirmary." suggested Ferb.

Curious, Isabella noticed that there were toothbrushes inside the bathroom, as Buford had tipped over the cup that they were inside in.

This gave her an idea.

Immediately, she pulled out a toothbrush and brushed her teeth with it.

She then began to approach Knightbrace.

"Hey there! How would you like to share my toothbrush with me?" asked Isabella.

Knightbrace gasped in shock. Why would she even suggest that?!

"You should never share your toothbrush! Don't you know that?" inquired Knightbrace.

"I wonder what she's planning?" questioned Phineas.

Immediately, Isabella approached Knightbrace with the used toothbrush.

"I'll get you started!" shouted Isabella.

"Get away from me!" exclaimed Knightbrace.

Immediately, Knightbrace backed away from Isabella...

...and he ended up falling down the stairs that he had walked up earlier.

"Ow! Oof! Ouch! Ooh! Aah!" bellowed Knightbrace as he fell down the stairs.

"Well, that worked surprisingly well." noted Phineas.

"How long is our staircase, anyway?" questioned Isabella.

Ferb shrugged.

"Is he down?" asked Baljeet.

As it turned out, Knightbrace hadn't been defeated yet, though he WAS injured.

"This isn't over yet! How would you like some dentures?" inquired Knightbrace.

"Why would we need dentures? We're just children." questioned Phineas.

Immediately, Knightbrace wound up some dentures, then tossed them at Sector P.

The dentures began to advance towards them.

However, the Kids Next Door began to shoot at them, causing them to stop moving.

"No!" bellowed Knightbrace.

Isabella then whacked Knightbrace on the head with a frying pan and knocked him out cold.

"Ergh..." said the ninja as he passed out.

"Phew!" Isabella sighed in relief. It looked like Knightbrace wouldn't be causing any more trouble for the time being.

"Yes! We won!" bellowed Baljeet.

At that very moment, Buford got up.

"What happened?" asked Buford.

"Isabella beat this evil dentist..." answered Phineas.

"Congratulations, I guess." stated the bully.

About fifteen minutes later...

After they had defeated Knightbrace, Sector P decided that it would be best to send Knightbrace to the authorites, so they decided to give the Moon Base a call.

Fortunately, since they had rockets, they arrived at the treehouse shortly.

"Thanks for helping us catch this maniac...he's been tormenting children for ages." said Numbuh 362.

"Hurry up and get him inside so that we can take him to the Arctic Base already!" ordered Numbuh 86.

"Wah!" cried Knightbrace as he was loaded into a Kids Next Door vehicle.

"We're working on it!" exclaimed a member of the Kids Next Door moon base.

"Please let us know if you manage to capture any more adults that engage in tyranny over children." answered Numbuh 362.

"There do seem to be a lot of them." noted Phineas.

"Well, not many adults actually do engage in adult tyranny over children...but unfortunately there are still enough to make you nervous. Especially Father." remarked the leader of the Kids Next Door.

"I see." nodded the boy.

Immediately, the Kids Next Door vehicle sped off into the distance.

"So, I wonder what Sector V is up to." questioned Isabella.

"Beats me." answered Baljeet.

Meanwhile...

At the Sector V treehouse, the Kids Next Door weren't feeling too well.

"Ugh..." murmured Numbuh 2.

"It looks we ate too much candy..." remarked Numbuh 4.

"We've got to watch how much we eat..." noted Numbuh 3.

"I guess you're not used to eating as much candy as I am." suggested Numbuh 5. Strangely enough, she was feeling fine.

"I'm glad that we decided to share some of it with Sector P..." noted Numbuh One. He hadn't eaten much but he was feeling a tad ill anyways.

It looked like they were just going to have to eat a bit less next time.

Unbeknownst to them, they were being monitored by a certain individual. For some strange reason, he had a lot of snot dripping down his nose.

"The entire Sector V is sick...it must be my birthday." remarked said individual.

Immediately, he walked off to look for more kids. They probably were more healthy than Sector V was...he could probably rectify that.

And Knightbrace is down...after this Sector V is going to start feeling rather sick...yet another villain is going to show up. It's up to Perry the Platypus to save the day! Because you know, he's a semi-aquatic mammal of action.

And yes, he's fighting another scientist of sorts. Fighting evil scientists is what he does best...and of course being a mindless platypus.
