Guest Reviews

LOTCR: Yes, of course I like it. While my current profile image has LEGO Frodo, I've always been a fan of LEGO. It took me two days the first time through to play "LEGO The Lord of the Rings". I still play the game every now and again. That darn phone of yours. I hear you.

Okay Frodo, I think you've crossed a line since some of us have stayed at the hospital before.
Frodo: Oops! Sorry about that, Aria.
It's fine. You didn't remember when you said all of that.
Frodo: I was referring to other fangirls, not to you. But still, you are a bit crazy. Just don't go too far again. I wouldn't want to straighten you up.
Don't worry, Frodo. I'm doing my best to make sure that doesn't happen again.
Frodo: Good. I'm glad.
As for that speech Frodo, I think you're doing too much quoting on Bilbo's behalf.
Frodo: *chuckles giddily* Well, Bilbo has learned from the best.
Uh huh.

I'm glad. Keep sending those sweets! -Frodo and everyone else: Yay! - Well, I only said that because this is what I've been doing. I don't know really how Frodo would react to other girls and women. Well, maybe I do. –Frodo: Yeah right…- Oh never mind. Okay, great! Yay for Fatty! –Fatty bows, telling everyone to settle down- Its fine. We don't know yet how Frodo would do in an actual game, but that is coming up, I just don't how long or how soon. We'll see.

You're forgiven and I'm sure DoctorWhovian18 will forgive you as well. –Legolas gives you a nod, accepting your apology with a grin- That's what I thought, but I was just checking. No, I didn't think of you in that way, since I am against slash. I'm glad to know now. No hard feelings.

Thanks. However, you should thank DoctorWhovian18 as she's the one who gave me the ideas for almost all the pranks in the last chapter. One prank was my idea and it was inspired by Boy Meets World, the Halloween episode in Season 1, something which I noted in the previous chapter. Yes, I know, poor Sam. I'm glad you gave him a cupcake. –Sam agrees, while still shy around me- It's all right, Sam. Yup, you do.

Because Halloween is a time where no is who people think they are, the students who you think are wearing the costumes may or may not be who you thought. If you are right or wrong, why not read this chapter and find out. You may be surprised.

Around the same moment when Pippin was scaring his sisters, somewhere in the castle, Frodo and Fredegar, still dressed in their costumes, were inside the Boathouse. Frodo was certain this was the spot. Perfect! The Black Lake looked deep enough here: not too shallow and not too deep. It would be enough to scare Merry.

"Frodo, are you sure about this?" asked Fredegar.

"After the scare he pulled on me, I'm willing to try this out on him," said Frodo, determined.

"Wasn't it Pippin who gave you that party popper?" asked Fredegar, certain this was a misunderstanding.

"Who do you think instigated the prank? Pippin was just following orders," said Frodo. He stopped as Merry approached.

Merry asked this question as he ran up to Frodo and Fredegar, "Who was following orders?" Merry was still dressed in his costume.

"Well, no one. But Fredegar wanted to see how deep the water was," said Frodo.

"It certainly looks deep, but I'm not going in," said Fredegar. He truly was afraid of what lurked in the Black Lake.

"I'm sure it's not that bad. But we're in costume, so any chance of swimming would be futile," said Merry, speaking the truth.

"Yea, you're right. But at least look at the water, Merry, and see how deep it is," said Frodo.

"Here? Now. Oh, you two are chicken. And you can't swim, Frodo. Is that right?" asked Merry.

"No, I can't swim. But here why don't you take a closer look," said Frodo, inching Merry closer before backing away.

Merry looked over, but couldn't see anything. "Where? I don't see anything."

Frodo looked at Fredegar for a moment. Then, unexpected even to Merry, Frodo pushed him in. Merry hit the water like a heavy stone. The lake looked so green. Merry hardly heard Frodo's voice as he plunged deeper and deeper into the water.

The water felt so cold. He tried to swim as hard as he could, and made some progress kicking. Good thing his costume was lighter than Frodo's, but then Frodo's costume didn't have a thick, round belly. Why on Middle-earth would Frodo do this to him? It's not like he instigated… oh wait, he did when he told Pippin to hand the party popper to him. How did Frodo catch on? Oh good, the surface was close now.

It only took Merry a couple of seconds to hit the surface. He was drenched. The Black Lake at least allowed him to cool off, but Merry was shaken up as well as alarmed. He asked Frodo, who was laughing his full head off, "Why did you do that?"

"I know it was you who told Pippin to give me that party popper!" accused Frodo, pointing his index finger at the soaking-wet hobbit boy. "Next time Merry, be the one who is pranking, not the one who initiates the pranks so you can send somebody else to do them."

Merry climbed up the stone ledge, completely out of his place. Frodo added, "And that was for the number of pranks you pulled on me in the past two months!"

"Here! I didn't think I did anything wrong," said Merry, not understanding his punishment.

Frodo chuckled, "That you did, Merry. That you did."

Merry was out of his wits. Could he and Frodo still prank people on Halloween? Just like that, Frodo used his hand magic to dry Merry off. Even though it was silent between the two hobbits, Frodo and Merry still returned to the castle with Fredegar, convinced they needed to pull more pranks on Slytherin students. At least the good thing was there was some sort of unspoken truce between Frodo and Merry… well, within that time frame.

o-o-o

As Snape walked down the corridor, he found Draco Malfoy talking with his friends Crabbe, Goyle and Lotho. What was Draco doing without his mask? Something was fishy here. He figured he should ask anyway.

"Mr. Malfoy!" called Snape. Malfoy advanced towards his professor, wondering what this was all about. "I noticed you're not wearing a costume. Last I saw you, you were wearing a Jarvey mask."

Draco was appalled. "I'm not wearing a Jarvey mask, and I certainly do not have a costume."

"You're telling the truth?" asked Snape.

Draco confirmed as much. "Every word, professor."

Snape was confused, but convinced by this statement. "Very good. Run along." He watched Draco return to his friends, right as they wandered down the Dungeon corridor.

This was puzzling. So Malfoy did not have a Jarvey mask of any kind. What kind of sorcery was this to pull tricks on other wizards? True, it was Halloween… this was too painful to solve. Not wanting to deal with the issue anymore, figuring the students pulling these costume pranks would be punished for their crime, Snape returned to his office. He about had enough of these shenanigans as it was.

o-o-o

As soon as his last class of the day got out, Lotho headed straight for the dungeons. Even though it was one of the coldest places in the castle, the dungeons were growing on him. He felt so happy there, more himself. He could be whatever he wanted…

"Bzzzz…"

What was that obtrusive sound obstructing his thoughts? He had to find…

"WHAAAH!" screamed Lotho.

Standing before the Slytherin first-year hobbit boy was another student, dressed as a Vampyr Mosp. This Vampyr Mosp costume looked so real, and it was inching closer his way in some kind of creepy, menacing way. Oh how he hated insects right now, especially magical ones.

"LEAVE ME ALONE! FIEND!" screamed Lotho, doing everything he could to back away from the monstrous insect.

"Bzzzzz… Bzzzzz…" The insect's mantra continued, buzzing faster and faster as the student swarmed in.

Lotho eventually could not take it no more. He found an opening in the corridor. As he ran off, with the insect chasing after him, Lotho cried, "You'll never get past me! I'm a Sackville-Baggins, and that means loyalty!"

"Bzzzzz…. Bzzz Bzzzzz…" The student's insect costume sounded like it was questioning him. This ticked Lotho off on the spot.

"Just leave and pester someone else," said Lotho, furious. As he walked down the corridor, he noticed the insect was chasing after him. "Get away from me!" Lotho sped up his pace, and the insect sped even faster. Strange how this student dressed as the Vampyr Mosp was a few inches shorter than he. However, Lotho didn't have much thought into the manner of height, he was too busy fleeing from this annoying student.

At last he made it to the wall that led to the Slytherin Dungeon. He stopped the student in the Vampyr Mosp costume from entering. "You can't follow me. We Slytherins would know about it, unless you're another student from Slytherin…" No response. "Suit yourself, you little twerp. I'll have you…" He was cut off as the wall closed after him.

The student in the Vampyr Mosp costume shrugged his shoulders. He returned to scaring other Slytherins. It felt good to scare them, since it gave them a taste of their own medicine.

o-o-o

The Halloween feast loomed on the students; for that evening, all the students and staff filed into the Great Hall. The ones that arrived last were the five students dressed up in their respective creature costumes. All the students pointed and looked at them all as they departed for their separate houses. Lotho could now see that none of the students were in Slytherin, for three were in Gryffindor, one was in Hufflepuff, and one was in Ravenclaw… wait a minute!

The student in the Vampyr Mosp certainly did something. When Lotho turned next, he could see the mask and costume was gone and Frodo Baggins was present. Where had he been? Wait a minute! Oooh, he would get Frodo back for this. He would make certain of this vow.

The other masks were blown away as well, revealing the student who wore the Jarvey mask to be Merry Brandybuck, the student wearing the Purple Tree Frog mask to be Pippin Took, the student wearing the Salamander mask to be Fredegar Bolger, and the student wearing the Shrew mask to be Samwise Gamgee. These reveals made Lotho flabbergasted, but more determined to get his revenge upon the five hobbit boys. He was already suspicious as to how these five hobbit boys had obtained their costumes and masks. However, the five hobbit boys in Gryffindor, Ravenclaw, and Hufflepuff were still wearing the rest of their costumes, just not the masks anymore.

Frodo, meantime, was busier staring up at the ceiling and also the feast before him than to see Lotho's disdain. At least the bats flying from the walls and across the ceiling were live ones, but the live ones scared him more than the ones he set on Merry and Pippin, when Frodo had control of them. And yes, Frodo did see the thousands of pumpkins lit and floating above his head, which he figured meant in celebration of Halloween. He still couldn't get enough of food appearing on the gold plates.

As Frodo ate some of his cooked carrots, Professor Quirrell burst into the Great Hall. He was acting like a madman and screaming about a troll in the dungeons, seconds before he fainted in front of everyone. There was much screaming amongst the students afterwards. Merry and Pippin screamed at each other, while Fredegar was alarmed and wanting to flee the scene. Lotho wanted to settle things right then and there and was pushed by a couple of students trying to leave the Great Hall. Sam closed his eyes due to all the screaming, but his sisters freaked out. As for Frodo, the second everyone freaked out and didn't pay attention to him, he used his hand magic to camouflage himself, making him transparent to his surroundings and other students. While everyone freaked out, Frodo made his way to staff section. The second Merry spotted him he ran towards him, grabbed Frodo's costume and also became invisible.

Dumbledore spoke aloud to everyone, once they quieted down. "Prefects lead your houses back to the dormitories immediately!"

Just like that, everyone that was a student filed out of the Great Hall. Well, almost every student. Pippin wondered where Merry had run off to. Confused and feeling alone, Pippin chased after the other students.

Frodo whispered low to Merry, as he jerked his hand off his costume, "Get – OFF – me! No wait… here." He used his hand magic to keep Merry camouflaged, in spite of Merry almost turning visible. He quickly led the way, as he spotted Snape fleeing the scene quickly. "Come on, Merry. Let's follow Snape."

Merry whispered low to Frodo, "Okay."

Snape was quick, forcing Frodo to chase after him and Merry. They were lucky Frodo had muffled their footsteps, so even Snape could not hear them. What Frodo and Merry could see were watery reflections of their surroundings, as if an invisible water shield was protecting them from others' sight. At last, Snape and the two invisible hobbit boys reached the forbidden corridor.

The third floor corridor on the right-hand side looked foreboding enough. Merry, in a way, felt this corridor was not something he and Frodo should trespass into, especially since they were following Snape. Glad to hear Frodo's footsteps, Merry continued his chase after Snape, and slowed down as Snape drew closer to an unlocked door. Somebody was inside, but whom?

Frodo panted as he caught up to Merry. Relieved they were still invisible, Merry snuck closer to the door. Frodo crept inside the room first, with Merry following after him. Merry stayed by the door, keeping it ajar, and watching the scene from there. He couldn't see much, but could hear Snape and what sounded like Quirrell in an argument.

Frodo, unlike Merry, witnessed just enough of the scene:

"Pr-Professor S-Snape, I-I-I was on-only…"

"What do you think you're doing in here?" snapped Snape at Quirrell.

Quirrell, ignoring Snape, continued his search for something. However, he was pushed by Snape, right as a three-headed dog bit Snape in the leg. Frodo moved as Quirrell sped towards the door. Merry jumped back as Quirrell made it out of the room. Snape used a nonverbal spell on the dog, putting it to sleep, if only temporarily. Frodo was lucky he wasn't caught, for he made it out of the room seconds before Snape and crashed into Merry. Frodo looked back at the door, where Snape locked it and followed Quirrell back in the other direction.

Moving off of Merry, Frodo whispered to him, "Let's head back to our common rooms."

"Sounds like a plan." Merry whispered back.

"I'll use my hand magic to take off all our costumes. I think I can manage." Frodo did just that and the costumes were gone from him and Merry, He did not know if Sam, Pippin, and Fredegar shared the same fate, or if the three were waiting on the seventh floor for them. At least he got his costume and Merry's off, returning to their school uniforms they had on that day.

In quick procession, Frodo nonverbally camouflaged him and Merry again. They were lucky Snape and Quirrell didn't see them or catch them, giving them an ample opportunity to follow them down the corridor. At last they reached the door to the Grand Staircase. Snape and Quirrell took it, fleeing the scene and heading downstairs. Frodo and Merry charged up the stairs. They arrived on the seventh floor where Fredegar and Pippin waited for them. Frodo, after turning him and Merry visible again, used his hand magic to make the costumes vanish, leaving Fredegar and Pippin also back in their Hogwarts' scarlet-and-gold Hobbit school uniforms.

Relieved to see their school uniforms again, Fredegar and Pippin said to Frodo, grateful, "Thank you, Frodo."

"I wonder where Sam's at," said Pippin.

"Probably avoiding Frodo," said Merry, shaking his head. "Doesn't he know that Frodo can use his hand magic to restore his Hobbit uniform? He's going to look like a fool tomorrow."

"Well, he won't get far. Those costumes don't go off unless I say," said Frodo.

"Unless he's found a way to take it off," said Pippin.

Frodo thought it over, and softly, without anyone noticing, Frodo managed an effort to help Sam take off his Shrew costume, while leaving the mask attached. Even though Sam was a distance away, Frodo could somehow feel that his hand magic worked. How it did its job Frodo did not know, but he felt it. After saying his farewells to Merry, Pippin and Fredegar for the evening, Frodo returned to Ravenclaw Tower, where food had been sent up. It had indeed been a fun-filled prank day.
