Here is a parody of the episode: SpongeHenge. Also, we are nearing the end of the Sponge House.
In the middle of the night at the Loud house, someone sneaks into Lily and Lisa's room. Lisa is sound asleep and someone wakes her up. Lisa groggily begins to stir awake and looks up to see her third eldest sibling, Luna, pointing to a big scarf wore around her neck.
Luna: [hoarse voice] Sorry sis, but I need your help. It's urgent.
Lisa: Ugh, what is it now, elder sibling?
Luna: As you may see, I've got a sore throat and the doctors said I won't be able to recover until maybe a week. This is way whack bro, particularly as Mick Swagger's coming to my school today for a special celebrity greeting event, and I can't stand not being able to show my vocal talents to him like long ago (this is a reference to the official episode House Music).
Lisa: So you expect me to come with some kind of cure to your little ailment over the course of this night? I may be a genius and I love willing test subjects, but even I have my limits Luna.
Luna: No, no, no Lisa. I don't want you to merely cure me. I want you to ENHANCE my voice, make it so birds flock to me every time I open my mouth. I intend to be more than just good to my idol, but perfect with my singing chops. You feel me?
Lisa: [she sighs before responding] Fine, I'll create something in relation to what you desire, but you owe me for me losing my sleep for this occasion.
Luna then hugs her younger sister as a way of saying thanks before the super genius gets to work while the rockstar goes ahead and covers Lily's ears with noise-canceling headphones to ensure she doesn't wake up to anything from Lisa's experimentation process. After several hours, Lisa manages to create a single blue pill that she hands to her sister.
Luna: Thanks sis, I owe you one.
Lisa: [yawns] Precisely. Now I'm going back to bed. [walks back to her bed]
Luna soon rushes on outside the house for a test drive, swallowing the pill. The rockstar coughs up a bit as the capsule's effects are not immediate but slowly, she manages to vocally conjure such a wonderful tune even with how super windy it is and indeed cause birds to flock all around her and sing too. Then the sun goes up as it is morning now.
Luna: Oh, here comes the sun and I say it's all right. Well, it's been fun, little dudes, but I've gotta get ready for school.
As she heads inside, a bird follows her.
Luna: Quite a wind this morning, eh bird dude? [wind blows Luna away] Whoa! [more birds come] Hey, Tweety, can you tell your friends I don't have time to hang right now? [the birds tickle her, Luna laughs uncontrollably] Hahaha! No, please! Stop it! Please stop! [continues laughing, until Luna lets go of the rocks] Whoa! [Luna flies into the front door, opens it and enters the house] Oh! I'm going to be late! [the birds try to get into the house] I told you guys, I don't have time to hang out! [Luna closes the door and goes to her room to get dressed]
Cut to Luna dressed in her usual daytime attire. The birds fly up to her window and peck on it with their beaks.
Luna: [sees the birds] I need to call in some help. [calls Leni on her phone] Leni, I need you to drive me to school.
Leni is shown to be at the high school already.
Leni: But I'm already at school.
Luna: Wait, when did you get to school?
Leni: I drove here like, thirty minutes ago. I'm volunteering as the nurse's assistant.
Luna decided not to question that since she really needed to get to school.
Luna: Well, I need your help. These birds don't want me to go to school.
Leni: Birds?
Luna: They're attracted to my new enhanced singing.
Leni: Uh, I don't know what enhanced means. But if it's transportation you need, I know just the thing.
Leni rushes to the parking lot and spots a junkyard truck with a winch. It belongs to a teacher but she borrows it when no one's looking. She starts to drive back to the Loud house and soon arrives. Luna opens her window to get her older sister's attention.
Luna: Leni, up here!
Leni controls the truck and gets the winch up to Luna's window, attaching the rocker to it and then dragging her off through the roads all the way to Royal Woods High with Luna keeping her mouth shut. Leni has arrived back at school.
Luna: [wore out] Thanks dude.
Cut to Luna in music class where Mic Swagger is joining the class. Luna excitedly holds out her instrument, a clarinet, ready to impress.
Mic: Luna, love. Long time, no see?
Luna: Mic, it's so awesome to meet you again in person. I'm ready to perform for you.
Mic: Well, show me what you've got, mate.
Luna begins to perform a clarinet solo, but then there's a strange and annoying tapping sound that causes her to lose her focus and rhythm.
Mic: You alright?
Luna: Uh, yeah. Let me try another instrument. [picks up a xylophone and begins to play it, but the tapping sound is heard again and it causes her to mess up again] Um, the xylophone isn't really for me. Oh, I've got it! [picks up a guitar] Now this is my best instrument. [begins to play the guitar and rock out. Mic is impressed, but then the annoying tapping is heard again and Luna turns around in anger, having enough of it. To her surprise, it's the birds from earlier trying to break through the windows to which they do]
Luna: Oh no. They've found me.
The students start to freak out as the birds swarm into the classroom, and towards Luna.
Luna: No, no, no, guys, please! Uh, would you mind coming back after school? Heh, I'm trying to work here.
Suddenly, the roof of the school gets blown off due to the strong winds. The students panic and the staff gets them to huddle in a corner. Luna's friends and her sisters, Luan and Leni, huddle in a corner trying to stay down. Unfortunately, Luna is unable to join them as the wind sends her launching in the air. The birds follow her. The musician is then seen landing on Mr. Grouse's house and she grabs onto the weather vane, hanging on for dear life as the heavy wind continues blowing. Inside, the elderly neighbor is watching tv.
Weatherman: The weather situation is much worse across the country.
Bob: And this doesn't look like the winds are going to stop any time soon. [TV reporter gets blown away and Mr. Grouse laughs at this]
Barbara: And that's the way it is in your world today.
Mr. Grouse: [clicks through the channels] What else is on? I don't want to watch any of this boring stuff. I wanna watch something decent like-
Suddenly, Luna falls through the chimney.
Mr. Grouse: [startled] What the-?
Luna: Sorry, Mr G. I need a place to hide from those birds.
Mr. Grouse: What birds?
Luna: Ever since I took Lisa's pill, it gave me the singing voice of an angel that these birds seem to love. [the birds are heard and they come in through the chimney]
Mr. Grouse: Um, nice birdy. [bird pecks Mr. Grouse] Owww! [Angry] Luna, get out of here! [he pushes her outside and the birds follow] It's bad enough I have to deal with a family of thirteen, but I don't need to deal with birds too!
Luna: [sighs] At least the wind stopped. [birds peck Luna. The rock teen makes a run for it, and soon hides in cave] I think I lost them. Well, I guess I should just stay here where it's safe... and quiet... and dark. It's okay. I'll only hide out here for a second. Yeah, it shouldn't take long. Behind these rocks. These sedentary, lifeless rocks.
Later…
Luna now looks absolutely crazy with long hair, tarnished clothes, even yellow teeth with some of them missing. She is sitting together with an exact stone replica of herself.
Luna: Hey, dude. Just thought I'd spruce you up a little. Auh-what's that? Oh, you don't say. Well, guess what. You're my best friend too. Mmm-hmmm. Come on, let's have some fun. Look buddy, mmmmmmmmm. Dinner's ready. Here, let's have some tea. Want some sugar, bruh? Hmm? One lump or two? Oh, you can have it all. [puts all the sugar in the tea] I feel comfortable around you. [sugar crumble in mouth] Can I confess something? Cause I know you'll understand. I have this problem. I seem to attract birds! Hahahaha! How do you handle a thing like that, Hmmmmm? [Luna stone stays still] Yeah, yeah. I'm at a loss, too. [regains her sanity] Oh, bogus dude! I'm gonna be stuck in this cave forever! [sighs onto the Luna stone replica and it makes a good tune as the wind blows through its open mouth] Of course, dude. Brilliant idea!
Luna takes the stone outside.
Luna: We'll see what happens this time. [birds come] Whoooaaa, here they come! Go get 'em, buddy! [birds hate the music and fly over to Luna] Hey, guys. Long time no see. Uh, what do you think about my little friend's song? [Luna's stone replica plays foul notes] ...Something wrong? [bird pecks Luna. She runs back to the cave] Hmmmmm. I created one stone Luna that uttered a note in a foul key. But if I were to craft another in a different size, [pulls down extremely complicated equation on a blackboard] the dimensions of that hollow center, multiplied by the number of holes, may offer another tune. One that could soothe those birds. But which one is the right size?! Eh. I guess I'll just have to make a bunch of them.
Luna gets to work, making the eight musical stones.
Luna: Okay, that should do 'er. [stones produce melodious notes in the breeze which attract the birds and they love it so much that they completely forget about Luna] Whoa. It actually worked. Ah, they're finally leaving me alone. I can go back home now! [laughs] Loud house, here I come! [Luna gasps and stops running] How long was I gone?! [She finds the buried remains of her home] No! No! No!
She screams and cries in despair. However, someone inside the house comes out to greet the distraught Loud teen: a much older and similarly disheveled/crazy Lisa.
Lisa: Luna? My third eldest sibling?
Luna: [looks up to see her genius sister] Lisa? W-what happened?! Is everyone okay?
Lisa: [sighs] I'm afraid I'm not sure, dear sibling. The other family members got blown away by that outrageous wind years ago. But I resorted to staying in my bunker. Ever since then I haven't seen or heard from them.
Luna: [shocked] No. It can't be.
Lisa: Unfortunately, it's true. But fortunately, I've been working on a time machine so we can go back in time, stop my past self from creating that pill I gave your past self long ago, and thus prevent this disaster from ever happening.
Luna: Well, I'm in. Let me give you a hand, I've got nothing better to do anyway.
Cut to a montage of Luna assisting Lisa in finishing up the time machine, with Luna giving Lisa the parts she needs as Lisa follows the design on her blueprint, and soon the time machine is completed.
Lisa: Success! Now let's get going.
They enter the machine and they travel through time, going to the past. Cut to the past where past Luna is asking past Lisa for the magic pill, but suddenly the time machine appears in Lisa and Lily's room, surprising the past selves. Future Lisa and Luna come out.
Future Lisa and Future Luna: Cease/Stop! Don't do it!
Future Lisa: Sweet mother of Einstein! It's our future selves!
Future Lisa: That's correct! And we come with a warning, you mustn't create that pill! Trust us, it will lead to disastrous results!
Future Luna: I'm doing this for your own good, past me! [Luna grabs the pill maker and destroys it by throwing it in the ground, breaking it and then smashes it to pieces, past Lisa is shocked]
Future Lisa: We had to do what we did.
Now because the pill machine is wrecked, it causes the future siblings to fade away into nothingness because of paradox reasons.
Luna: [relieved, with a sore throat] Well, I'm glad our future selves gave us that warning. We should totally trust them. Besides, there'll be other days to impress my idol.
Lisa: [disappointed] Well, that's just terrific. I wish they would've told me before I spent hours working on that invention. It was all for nothing. But it was intriguing to see our future selves.
Luna: Yeah, dude.
In an alternate timeline, 3,000 years later…
The three aliens and their guide float down to Luna's stone statues.
Alien: To this day, no one knows why these mysterious statues were created or by whom. [One alien takes a picture with its mouth] All we know is that the genius of their design has caused the annual migration of birds to their wondrous tune. [birds come and listen to the angelic singing coming from the open mouths of the Luna stone statues. Off in the distance, a guitar riff from Luna is heard and there is a zoom in on one of the statue's mouths.
