"Buuuurrrp!" Loona continued having her "biccups" erupt from her system. To her, this was so embarrassing. Her burps were enough to mildly make the ground shake like a brief earthquake. It was even powerful enough to knock some of Flip's merchandise off the shelves as well, and break some objects filled with glass.

"good gravy!" Flip said. "What the heck was that?"

"Nothing." said Lincoln and Loona in unison. "Just have a bad case of hiccups." The female disguised hellhound added

"Oh dear. Well you've come to the right place if you wanna get rid of them." He pulled out a toxic waste barrel and it had some glowing green liquid in it. "Vegetable juice max. Made with dried moss, plants, cactuses and other green stuff."

"Fuck nah!" Loona said. "That looks like it can poison someone."

"Poison?" Flip said. "Now where would you get something like that?"

"Don't listen to him, Loona." Said Lincoln. "Never trust Flip's 'medical professions'. Ever."

"we'll figure out a way to get rid of the- buuurrrp!" The disguised hellhound hiccuped again, making the ground slightly shake again. "Come one, squirt, let's get out of here."

"Maybe my sisters can help you."

"Right, that little genius sister of yours." Loona remembered. "But I am not having her probe me or dissect me or any crazy shit like that." She heard a woman gasp and she had a kid with her, clasping his ears in anger and walking away. "What are you looking at, you slut?" The female hellhound just retorted at her.

The mother just walked away in anger. "Don't worry, Lisa can do almost anything... except make arts and crafts."

Loona couldn't help but laugh. "And yet she is a little girl? How embarrassing."

"Yeah, even Lisa has a weakness." Walking down a few blocks, Lincoln heard another biccup from the disguised demon. "Whoa. Maybe you should try holding your breath."

"Meh. Why not?" Loona took in a very deep breath and after exactly second seconds, it sounded like her biccups were gone. However, she let out another "BUUUUUURRRRRRRP!" From herself. A longer, and more powerful one that made many car horns go off and people falling on the pavement and streets, and cyclists falling or flipping over. It even made a car go radically off-course and crash into a fire hydrant, and the airbag went off at the driver. "Oops." Loona said.

Worriedly, she and Lincoln hurriedly went all the way to the Loud residence to try and figure out a way to get rid of Loona's biccups, leaving everyone looking around and exclaiming words of confusion. Good thing they didn't know what Loona's real species was, or there would have been a big problem.

Loona let another another biccup from her system and it made the trees nearby rumble. "We need to do something about this." Lincoln said

"No shit, Sherlock." Loona rolled her eyes. "Good thing Tex isn't around seeing me like this right now."

"Come on, he's one of your closest friends."

"Exactly. It would be embarrassing to do it in front of your best friends." Loona pointed. "But hopefully, that nerdy sister of yours can "Buuuurrp!"

"Don't worry. she can try to help you any way she can." Lincoln said. Loona didn't have her expression changed. She just had her usual, blank expression on her face.

In the house, Lana said: "I swear, it was like an earthquake. How else would the ground shake?"

"Maybe Lynn's burping or farting?" asked Lori

Lynn gave the eldest sister a glare. "Hey, my farts or burps are not that powerful! Or, maybe it was you! We know about your secret farts, Lori." the eldest sister gave the sports girl a glare of her own

"Oh yeah, well you've probably been eating too much fire burgers from Burpin' Burger again! You're literally the most disgusting sister in the world!"

Lana cleared her throat and pointed: "Hey! I resent that!"

"Sorry, i mean, Lynn is literally the second grossest sister in the house." Lori realized.

"Well it is certainly not an earthquake." Lisa said. "We're not really near any oceans. Unless... unless it was powerful enough to hit California and come all the way across the United States."

"You guys are all wrong." said Lincoln, coming in the room with Loona, who changed back into her true Hellhound form. "Loona has the case of the biccups, and we need help getting rid of them."

"Biccups?" asked the sisters in unison.

"Burping and hiccuping at the same time, it's a Hellhound thing." Loona pointed.

"How did you even get that dude?" asked the rocker sister

"Well Luna," Lincoln cleared his throat. "Loona got herself the biggest soda that Flip had at his gas station."

"Ah. And I take it she drank it so fast?" asked Lucy

"So what if I was?" Loona sounded offended

"Nothing." said the Goth girl. "I wasn't judging you."

Then the female hellhound let out another biccup from her throat, making the ground slightly shake. Lily was giggling since she thought of it kind of fun. Something similar to a carnival ride for her. "Again! Again!" Lily clapped her hands happily.

"Remarkable discovery." Lisa said. "Another ailment from Hell discovered by yours truly."

"Yeah, well, too bad you can't really tell the whole world." Loona sang as she crossed her arms, then she let out another loud biccup.

"Ok, what is that?" shouted a female voice. It was Rita, who was coming out of the master bedroom downstairs with her husband. "Was that an earthquake?"

"Nope. biccups." said Loona. "hellhound hiccups."

"Oh." said Lynn Sr. "Why not just drink plenty of water to help with that?"

"You're not my life coach, but ok." Loona rolled her eyes.

"I didn't say i was your life coach." the dad pointed

"I didn't say you did." the female hellhound went into the fridge and got herself a large cup to fill the water up, and put some ice in it to keep it cold. It wasn't really a cup, but it was like a measuring cup used for baking food or similar dishes, and the female hellhound gulped the whole drink down, including the ice cubes, with five single gulps down her throat. Everyone was silent, and so was Loona as they were waiting for results. It took ten long seconds, but then Loona let out another biccup. "Shit" she said under her breath

"We heard that." Rita sang.

Loona just rolled her eyes in irritation again. "Looks like we'll try something else."

"Well, while you all figure out." said Rita, "Me and your father are going to go out for a little food shopping kids. please do something about those biccups before she shakes the house to its foundation."

"We will." said Lincoln. As the parents got out of the house for their shopping, Lisa came up with a brilliant idea.

"Eureka!" she said. "i think i know of a good formula to remove those biccups. But it might take a little time. Probably up to... ten to fifteen minutes."

"But what if she accidentally destroys the house?" asked Lana. "I don't want to be buried alive."

"We can... try old-fashioned ways to get rid of those hiccups." said Luan. "like... have you hang upside down and drink more water."

"Ooh, or we can use her as a pinata." said Mr. Coconuts.

The female hellhound got angry and grasped her hands around Luan's cheeks. "Try that and I will bite your heart out!" she threatened the comic sister.

"What? It wasn't me, it was Mr. Coconuts!" Luan said.

Growling, Loona asked Lincoln. "Does she even know that she is Mr. Coconuts?"

"Just play along, dude." the rocker sister sighed.

"Whatever." said Loona. "Is there a rope to hang me upside down?"

"got it." said Lola. "It's in the attic."

While they were trying to get rid of those burping hiccups manually, Lisa got to work in creating a cure for the problem herself. Loona was hanging and slightly dangling upside down from the rope in the living room with her arms crossed, and having her usual blank look on her wolf-like face. "Hope this doesn't fuck with my brain." she said out loud.

"It won't." said Lori. "Now we literally put more water in your mouth and see if those hiccups go away."

"I'll get the water." Leni sang. She got the same jug Loona got herself before, and filled it up with more water and ice cubes. "Hope this doesn't get water in your nose, Loona." she said to her.

"I've suffered shit way worse than that, Leni."

"And you won't eat my hand off, will you?"

The female hellhound looked at her in a weird way. "Dude, do i look like I wanna bite your hand off?"

"Do we have to be honest with you?" asked Lincoln. "The... attitude and how you are with Blitzo,"

Loona then let out a sarcastic laugh and back to her bored demeanor, she added: "Just shut the fuck up and let's get this over with."

"Rude." said Lola. Loona opened her mouth as Leni put the large jug of water in Loona's mouth, although she was a little reluctant since she knows the female hellhound can have a nasty attitude. Taking more big gulps, Loona was drinking every drop, every once of of water down her throat. Despite how much water she was taking in within herself, those biccups were not going anywhere.

"I thought it would work." said Lincoln.

"Perhaps she should try hanging upside down for a little while." said Lucy. "That sometimes gets rid of them."

"Guess i'll be like this as long as it takes." Loona said flatly. there she stayed; dangling and hanging from the ceiling by the rope and waited for results. Dangling and waiting, dangling and waiting, it looked like those biccups were gone, and the siblings began cheering in this supposed victory. Just as they saw the light at the end of the tunnel, there was another loud "Buuuurrp!" From Loona, implying that this was, too, a failure.

"Well that failed too." Lincoln said. "Man, I don't know what else to do to get rid of them. And I thought I was a man with a plan."

"Come in, don't be too hard on yours- buuuurrrp!" Loona said. "Everyone has a weakness, Lincoln. Like you said about Lisa and her ability to make crafts."

"I deeply resent that!" Lisa came down the stairs. "I admit, those kind of activities are not... my forté, but it does not mean I am... très terrible."

"Oh no?" Said Lola. "What about the time you tried to create a nice house for the school egg-"

"Do not mention that unfortunate event!" Lisa said. "You all swore you would never speak of it again!" Taking in a deep breath, Lisa calmly said: "Forgive my outburst."

"heh, and I thought I had anger problems." Loona smiled.

"Anywho." Lisa put her glasses back in front of her eyes. "I have created the perfect cure for your Hellish ailment." She pulled out a bottle of green liquid. "Behold, Biccup-Be-Gone. My newest invention that will get rid of those pesky hiccups faster than African painted dogs can catch a full-grown bull eland antelope."

"Ok, enough with the scientific bullshit, ok?" Loona sounded a little annoyed and impatient. "Sooner those biccups go the fuck away, the sooner I can get down from here."

"Of course. My apologies."

Lynn was the one to cut the rope and get Loona down from the ceiling. "Want me next time you do that?" Loona sounded irritated at the sports sister.

the hellhound just snagged the serum without thinking the smartest sister for the cure. Taking the potion down her throat, and waiting again, those biccups were indeed gone.

"They're gone." Loona smiled

"Hooray!" The kids said.

"you might want to hold on to that serum just in case."

"Nah, you keep it." Loona said.

"Don't you think you should literally thank her for creating the cure for you?" Asked Lori

"Don't you think that you should stop saying literally all the time?" Loona retorted.

"Ooooooh!" The other siblings said.

"Burn!" Luna said.

Lori just growled and said: "well-played."
