Summary: Without his great-greanddaughter knowing, Abraham tries to find out a way to move away from the hotel, due to Dennis' silly actions.
This chapter is the parody of the episode of the same name.
One early morning, Abraham was busy sleeping when he heard some weird giggling in the background. "Huh?", he said with confusion, before going back to sleep again.
The giggling soon resumed, and Abraham somehow figured out where the source of the giggling is coming from. He took off his sheets, and noticed that underneath them, was Dennis and Winnie. They were both wearing party hats, and blew noisemakers.
"Surprise!", Dennis and Winnie said in unison, "Happy birthday, Abraham!". Soon, there was a party downstairs, but the only people are Dennis, Winnie, and the man celebrating his 'supposed' birthday.
"Happy, happy, birthday! Happy birthday cake!", the two kids sang, while eating up cake. "Happy, happy, birthday! Pin the tail on the ghost!", they continued, while playing a party game. Finally, while giving out presents, the two kids sang, "Happy, happy, birthday! Happy birthday, Abraham!".
Eventually, the party was over, and Dennis and Winnie went out of the room, still wearing their party outfits. Abraham, who was more annoyed than ever said, "My birthday was LAST MONTH!".
"That's it!", Abraham said, taking off his party hat, "I'm moving out of this hotel!". However, he didn't want Ericka to know, so he decides to move away, without her, in secret.
Soon, Abraham was talking to someone on the phone. "Absolutely, Mr. Van Helsing.", the woman on the other side of the phone said, who was working for a mortgage facility, "I can definitely sell your room, in a flash.".
"Oh, that's great news!", Abraham said, "Because, I wanna move, as soon as possible.". "Alright then.", the worker said, "Well, as long as it is not infested with termites.", she said.
"There are no termites in the room that I'm living in.", Abraham said, and the worker soon interrupted, "Good, and as long as there are no obnoxious neighbors that live by you.". Abraham soon stopped, "Did you say 'neighbors'?", he asked.
"Yes.", the woman said, "I can't believe I'm saying this, but did you know, that 85% of our calls for someone who wants to move, has to deal with bad neighbors?". "No, I didn't know that. I...", Abraham tried to say, but was soon again interrupted.
"Anyway,", the woman said, "I'll be coming over to check the room, tomorrow. Ciao.", she said and hung up. "Dennis!", Abraham angrily muttered under his breath, "Nobody will buy my room, with him around here.". "Beside.", he continued, "Whatever a good neighbor like me would do, he would do the opposite.".
Suddenly, an idea sparked in Abraham's mind, and all he saying was, "Opposite, Op-po-site.".
The next morning, Dennis woke up to the sound of multiple musical instruments playing at once. "Huh? What's that?", he asked, as he jumped out of bed.
Walking down the hall, he sees his mom and dad, who are just as annoyed as Dennis. "Son, can you please tell whoever's making all the racket, to stop?!", Mavis said in a loud voice, hopefully for Dennis to hear.
Outside, it was revealed that Abraham was blowing a kazoo, banging a drum, and has a radio playing near him. Dennis went outside and noticed the senior citizen making the racket, "What are you doing with that drum?", Dennis asked.
"Drum? What drum?", Abraham asked, punching a hole into the drum and pulling out a wig. "This is just a wig case.", he said, before doing lots of silly tricks in his wheelchair. "Don't just stand there,", Abraham said, "Tackle me!".
"Papa Abraham, you need bed rest.", Dennis said, pushing the wheelchair up to the hotel, however Abraham stopped him. "Oh, I get it.", Abraham said, "You forgot what day it is, do you.".
"It's a lovable Wednesday morning?", Dennis asked, but Abraham interrupted, "More. It's Opposite Day!". Dennis was soon confused.
"You mean, you forgot? You've been missing out.", Abraham said, as he told Dennis that Opposite Day is the one day of the year, where somebody acts different. "Normally I'm grouchy, bored, and stuffy,", Abraham said, "but today, I'm silly, spontaneous, and carefree!".
"Is Opposite Day even real?", Dennis asked, and Abraham said it is, even saying that it's like a game. Dennis liked games, and he decided to play along too.
"Normally,", Abraham said, "you're very annoying and loud, so what are you going to be today?", he soon asked. "Quiet and out of the way!", Dennis said in a loud voice, however he knew he should be the opposite.
"I better 'Not' tell everyone about it!", Dennis joked, as he ran back inside. "So long, chum!", Abraham said, before saying, "And, goodbye Transylvania.".
As Dennis walked towards his parents, he said, "Goodbye, what a horrible night it is, right?". "Son, it's morning, and why are you saying goodbye?", Mavis asked.
"Cebause, today's Opposite Day, the one day of the year, where you get to act different.". Dennis told his parents, which makes them a bit concerned and confused. "Is Opposite Day real?", Mavis asked Johnny, as the two are watching their son move slower than before, "Yeah, but it's on this date.", Johnny said.
"Tinkles, it's Opposite Day, and I'm gonna...", Dennis said, before realizing what he's doing. "Walk, don't run. Now what?", he asked himself, thinking of an opposite thing to do.
"I'm just going to sleep in, and think about what I won't have in store for yesterday.", Dennis said, in a depressing mood. "Boy, Opposite Day is one of the most weirdest holidays I ever celebrated. Right, Tinkles?", Dennis asked, and Tinkles barked, before Dennis said, "Where's your holiday spirit?", causing Tinkles to meow like a cat.
Soon, there was a knock on his bedroom door. "Company, I HATE company.", Dennis said going up to the door in anger. "Who's there?", Dennis asked. On the other side of the door, was Winnie, so Dennis just said, "Go away, I never wanna se you again.".
This caused Winnie to cry, "Dennis doesn't like me anymore!", she cried, as Dennis opened the door. "That's right!", Dennis said, "You're my worst enemy." Dennis soon realized he went too far, as Winnie was having a temper tantrum in front of him.
"Winnie, you're not really not my friend,", Dennis said, saying why he said that, "It's just Opposite Day.". Winnie soon perked back up again, "Opposite Day?", she asked, "Hey I heard that. What's Opposite Day?", she soon asked, knowing that she doesn't even know about the holiday.
"Well,", Dennis explained, "whatever you normally do, today you do the opposite.". "I wanna try!", Winnie said, so she decided not to breathe, which Dennis told her to get her breath again, after her face was dark purple.
"Not that type of opposite.", Dennis corrected, "Let me show you how to do it, the WRONG way.".
All throughout the day, Dennis and Winnie had their Opposite Day fun, which started with themselves wearing their clothes with their colors mixed up, with Dennis wearing pink, and Winnie wearing yellow. Next, Tinkles was eating at the table like a human, because Dennis was eating like a dog out of a dog bowl, and Winnie decided to act like an actual dog, by going outside like normal dogs do.
Then, Dennis and Winnie blew bubbles, but it turns out that they were the bubbles themselves, and Winnie accidentally popped herself. Finally, the two friends had a conversation, backwards.
"Do you want to do some work around the hotel, worst enemy?", Dennis asked, with Winnie responding, "Nope.", showing her true holiday spirit, and the two friends laughed.
Meanwhile, Abraham was secretly trying to pack up his things, until Ericka came into his room. "What are you doing?", she asked, to which a very secretive Abraham tries to hide the evidence. "Nothing, just do your own thing.", he said, hoping trying to get her not involved.
Soon, Ericka walked off, and Abraham slowly pulled out his suitcase again. "Phew, that was close.", he whispered, "But the best part is: Not a peep or word from Dennis.". He soon chuckled under his breath, "Opposite Day, my best diversion yet.".
Suddenly, Abraham heard a couple of noises from outside, and went to the window to see what it was. Dennis and Winnie are both in their treehouse, however they are making it more messy than clean when Dennis said, "Nothing like spring cleaning, right?".
"What are you doing?!", Abraham said with anger. "Oh, hello Papa Abraham...,", Dennis said before he corrected himself. "Oops, I mean... Goodbye, Papa Abraham, isn't Opposite Day terrible?", he said while snickering, "And it's a dreary cloudy day, isn't it?", Winnie added.
Dennis and Winnie knew that it was sunny, and Abraham knew that the two kids took the joke literally. "I'll tell you what's dreary and terrible,", Abraham said, "I've never been so angry in my entire life!". "Wow,", Dennis said, "That's the nicest thing he ever said to me.".
"Opposite Day.", Abraham muttered, as he went back into the hotel, "Next time, it's going to be 'jump off of a cliff day'!". Suddenly he stopped, "If the real estate lady sees what happens to my room if those two hooligans mess it up, she'll never let me sell it!".
"I gotta do something!", he said, as he was now driving a bulldozer. "Outta my way!", he shouted, and Dennis and Winnie soon got out of Abraham's way, as he mended the treehouse, all by himself. "There,", he said, "Now don't do anything stupid!".
As Abraham was wheeling back to the hotel on his wheelchair, Dennis suddenly tried to figure out why Abraham's acting different.
"That's weird, Papa Abraham made the treehouse clean, when we had it dirty, which was really clean, so he made it dirtier. But then he cleaned the yard, which really means he's messing it up, which means that the opposite of clean is filth, and filth is clean. Which means Papa Abraham isn't Papa Abraham, he acting like Dennis!", Dennis said.
"What does that mean?", Winnie asked. "Well, it means I must be the opposite of Dennis, by being...", he said, as he soon went into the treehouse and opened the dress up closet, in order to find a white suit, and attached wheels to one of the chairs at the table. "Abraham!", Dennis soon said, mocking his step-great-great-grandfather's voice.
"Hey!", Winnie said, "I wanna be opposite too.". Dennis thought about it, and then said, "Okay, you can be Grandma Ericka!", Dennis said, pulling out a blonde wig, and another white suit, "After all, they are related".
"Yeah!", Winnie said as she chanted, "I'm Ericka, I'm Ericka, Ericka, Ericka, Ericka!", but Dennis soon interrupted her. "Wait, it's not just the looks that makes you someone else,", he soon said before going into a voice similar to Abraham's.
"You have to act like them too.", he said, "Ever since my great-granddaughter married my former enemy, turned friend, I have to nice to monsters, because of her new rules.". Dennis then tells Winnie, to said something in the style of Ericka's voice, but she instead chanted the same thing from before and Dennis joined in.
"After you, great-granddaughter.", Dennis said to Winnie, who responded, "Why, thank you Papa Abraham.". But while the two imposters are having fun, the REAL Abraham, was still packing up his bags.
As he was still packing his bags, Abraham realized he forgot something, and decides to go downstairs to find it. However, what he didn't know, was that the real estate lady has arrived.
"Wow.", she said, "This must be the legendary Hotel Transylvania.", and started to walk inside. Inside, she sees what looks like Abraham, but it was really Dennis in a costume. "Are you Mr Abraham Van Helsing?", the lady said, to which Dennis said in his pretend voice, "Yep, that's me.".
"That's strange.", the lady said, "I don't remember you having a small wheelchair when you talked on the phone.", but Dennis said, "Well, I... uh... somehow trying to lose weight, and this wheelchair is more my size.".
"Okay then,", the real estate lady said, "Tell me the condition of how livable the room is.". Dennis realized that the lady wants to know positive things, so with the Opposite Day trend going, he said, "The floor creaks, the roof leaks, and there's a terrible draft.".
As Dennis kept on talking about how harsh the room was, the real estate lady has gotta more concerned. However, Dennis barges her inside and shows her the 'worst' room in Abraham's living space, and that is Ericka's laboratory.
"Wow.", the lady said, regaining interest, until she noticed Winnie with one of Ericka's inventions. "And I'm guessing your Abraham's great-granddaughter, Ericka right?", she asked, and Winnie responded, "Yes, I am.", but when she turned around, the lady noticed that she has a face similar to that of a werewolf.
"Uh, is she supposed to look like that?", the lady asked, and Dennis replied, "Uh... she trying out of her latest inventions, which somewhat malfunctioned.", however, Dennis knew that the invention does work.
When Abraham and Ericka came back upstairs, with the latter not knowing why she was needed in the first place, they can hear a commotion coming from the lab. "What's going on?", Ericka said as she opened the door.
"And who are you two?", the lady asked, to which they are both Abraham and Ericka van Helsing. "I don't understand what going on!", the lady said, "He's Abraham, she's Ericka, YOU'RE Abraham, SHE'S Ericka! Are there any other Abraham and/or Ericka around here?!", she asked.
Suddenly, a meow frightened everyone, only for it to be revealed as Tinkles, who just like Dennis and Winnie, is wearing a white suit. "Oh, hi Tinkles!", Dennis said in his normal voice, "Happy Opposite Day!". "Opposite Day?!", both Ericka and the real estate lady said in unison, before Ericka angrily stared at her great grandfather.
"What?!", he said, "It's not like I'm going to trick Dennis and Winnie into thinking it's Opposite Day, just so I can move away from this hotel without you in secret.". When Abraham realized what he just said, Ericka got furious, and the real estate lady said, "I'm outta here.".
Wait!", said Abraham, "Don't go!". While Abraham was chasing after the real estate lady, Ericka was kinda impressed of how Dennis and Winnie have accurately made costumes that look like her and Abraham. "You almost had us fooled for a second.", she said, with a sly impression, showing to Dennis and Winnie that she wasn't mad at them.
"Why can't you just...", Abraham tried to say, but the lady said, "I wouldn't sell your room, even if you're the last Abraham of Earth!". She then eventually drove off, and Abraham is now permanently stuck at the hotel forever.
Soon, Dennis, Winnie, and Ericka went outside, with Ericka wearing an all black suit, and is wearing one of Dracula's capes, and they all said in unison, "Happy Opposite Day! We hate you!", showing that Ericka now has the holiday spirit.
But Abraham, all annoyed said, "Let me show you how... I HATE YOU!!!", and jumped into the bulldozer. "Grandma Ericka, do you think that Papa Abraham likes us, too much?", Dennis said, as he, Winnie, and Ericka soon ran in the opposite direction. "Happy Opposite Day!", Abraham angrily said, as he chased them from the bulldozer.
