With the Mega Weapon all but destroyed, the ninja knew they wouldn't have to worry about Garmadon trying to summon up any new monster or pirate army to try and stop them. Now they could focus all their time on training the now seventeen year old Lloyd. "You sure you don't mind having to age up so quickly?" Kai asked him one day. "We could always get you some Yesterday's Tea to revert you ba-"

"I gotta be on my A game if I need to fight dad, besides, now I can stay up way past nine PM and go out on missions with you guys!" He was growing stronger every day under the wing of his four teachers, but he knew he only scratched the surface of his abilities.

It was unusual to have so much free time, but no one complained. That is until later that day, the Serpentine radar installed into the Bounty picked something up. "What? But that can't be possible! All the snakes should still be in Ouroboros." Nya exclaimed. She managed to pinpoint the location deep in the Forests of Tranquility. "Odd I hadn't picked them up until now, must have been burrowing their way into the city."

"Pft, way off give or take a few kilometers. Perfect time for us to do some ambushing!" Jay grinned, readying his nunchucks for a fight. "Then we'll bring those oversized earthworms here for a little interrogation."

"Don't you think that's a little harsh?"

"They've done way worse to us, Zane. Besides, we can bet whoever's there could be planning something big! We're gonna put and end to it before it even begins!"

Suiting up, the five Ninja raced to the Ultra Dragon. "You best be on your guard, the forest depths are so shrouded that barely any light gets through the trees. Nya and I will stay back and keep a closer eye on the serpent's movements." Wu called as they flew off. "Hopefully it's nothing too serious."

"In the meantime I can try to find out what tribe it is, the radar isn't pinpointing the exact species yet, but it will once it's out in the open."

----------------------------------------------------------------------------------------------------------------------------------------

"Anyone remember to pack a flashlight? Hey Zane can't you light up your head like you did back at Darkly's?"

"It's only useful in smaller areas Cole, out in the open it doesn't have a lot of range. Maybe Lloyd's energy power can light a small fire?"

As he was about to do so, the Green ninja heard something slither by. "That must be our runaway snake! Alright... Now let's get ready for that ambush."

Of course it was much harder than it looked, having to fumble about in the dark with no way of knowing where anyone was. "Aha! Gotcha!"

"It's me you iceblock!"

"Oh sorry Jay. Now this time I think I have it! Oh wait this is a log. Do you think we-"

But before Zane could finish his sentence, a sharp pain surged right up his arm. "Ow!! It must be a Fangpire, I got bitten!"

Rushing in to aid his friend, Cole ended up tripping over his two feet, only to be bitten as well. "We could really use that light, Lloyd!"

"Hiiiiiya!!.... I think my foot went in its mouth. OWOWOWOWWOWOOWOWOOWWOWOWO!!"

With three down and only two left, Kai and Lloyd stood back to back in case their Serpentine foe tried to sneak up from behind. But what they didn't expect was for it to tunnel underground and pop up in between them, sinking one fang each into their ankles. "Grrr, it must have gotten away." Kai growled, rubbing his bite mark. "Weird, I don't feel any different. Jay you were bitten right? Does it feel any similar to Once Bitten Twice Shy?"

"Umm, just feels like something is pumping through my blood. If I start hissing when we get back then I can tell how we can change back without the staff.. But now let's get out of this dark, spooky forest!"

--------------------------------------------------------------------------------------------------------------------------------

Back at the bounty, the boys decided to take a rest and play some video games. "This here is supposed to be the scariest game of the year! Stalker Centipede!" Jay exclaimed, popping the cartridge into their console. "Oooh I'm so excited!"

Starting up the game, the ninja were all at the edge of their seats. However that wouldn't be the only change about to happen. "Huh? Ah!! What's going on?!" Looking down, the lightning ninja saw that his belly was inflating before his very eyes.

"Must be that snake bite, we're bloating up!" Zane theorized, panicking as he attempted to push his swelling belly in. All five ninja were puffing up at an alarming rate, it seemed the more they panicked the faster they rounded out.

Of course there's no way one could remain calm in such conditions, so in all the confusion they rolled about, bumping into one another like bowling balls. Their gi tore up the more they grew, leaving large gaps that exposed their boxers. It was as if helium was surging through their bloodstreams. Eventually they were all belly with only their hands, feet and heads sticking up, but only barely. Meanwhile the ceiling could barely contain the spherical ninja and broke instantly.

They would have floated off into the atmosphere if it weren't for the raised sail holding them down. "Oooh.. That was so weird. Umm, Kai? You're a little.."

Lloyd never got to be this close to the fire ninja, he didn't want to admit it but he grew to have a small crush on him. Their puffy cheeks just barely touched, making them both a little flustered. "Yeah I know. Kinda awkward isn't it? Nya!! Get us some weights and a really long rope."

"Huh? Was that you who broke the cei..." Thankfully they had anchored just on the outskirts of the city, or else Ninjago's protectors would have floated off into space. "What happened to you?"

"We were hoping you'd tell us, that snake we... Umm, tried to catch wasn't anything we've ever seen before. Must be a whole new species!" Jay replied, trying to float down to his girlfriend.

"New species? But Wu said there were only five Serpentine tribes, unless the one you found isn't native to Ninjago Island. I hope you don't mind me taking a blood test, I can try to extract its venom to pinpoint what it exactly looks like."

"Ummmm... Fine, but just this once!"

"How will you extract it from me? I don't have blood, only wires and oil."

"I'll scoop some up with a cotton swab from you Zane."

------------------------------------------------------------------------------------

It was obvious that the flying ship wouldn't be able to hold the now inflated ninja, so Nya and Wu had them rolled into the former's Samurai X cave. "Ya never told me you had a secret cave full mechs and stuff!" Jay exclaimed, weighed down in one of the four sleeping chambers.

"It's still a work in progress, but should be done sometime before Lloyd has to go up against Garmadon. Where is he anyways?"

"He and Kai are bunking together. Who would have thought a round of the world's scariest game could lead to this?"

"I managed to get venom samples out of your blood, it seems to expand the more your heart rate goes up. And using that DNA tracker I built, I should be able to find out what exactly bit you. Whether it be an undiscovered sixth tribe or maybe even a hybrid."

While three of the five inflated ninja were floating about in their rooms, Kai and Lloyd were trying hard not to face each other. After what happened only a few minutes ago, they felt too embarrassed to say a word. "Aw.. He is kinda cute, all round and squishy like that." The fire ninja thought, rolling onto his belly to face Lloyd.

"Kai is so handsome... There's no way he'd want to be with someone like me, but I don't think it would hurt to tell him how I feel.." Feeling something bump against his rounded rump, he yelped and bounced away, only to find out it was just Kai belly bumping him.

"Hey it's alright, no need to panic. We've already outgrown one room." Kai chuckled, wobbling his way up to the Green ninja's face. "Got someone on your mind? Ah! Something! I meant something.."

"I.. Umm... Actually there is someone. I.."

His chipmunk cheeks grew hot and pink as he continued to stare into the brunette's eyes, he was almost at a loss of words. He could feel his heart trying to burst right out of his chest, so he knew he had to tell him. "It's you Kai.. Um.. You're as hot as the fire you wielded." He sputtered out, blushing harder than ever.

"Aw.. Ya really think so? Because I think you're as sweet as your sick energy blasts."

With how much they were blushing they started to inflate once again, their bellies bumping once again as they surged outwards. Even their fingers and toes pumped up, making them look like overstuffed sausages. Their cheeks puffed up some more too, nearly covering up their mouths. All the swelling put a lot of strain on their gi, tearing them up by the seams and popping off them like buttons on a shirt.

Soon the duo were left in nothing but their boxers, but even they begun to tear up. But despite it all they just couldn't bring their heartrates down, they just wanted to keep watching each other bloat. Finally they had reached their limit, but now nothing covered them up. "Oh! Umm.. I didn't think we'd get this big.." Lloyd mumbled, trying to cover up his groin.

Kai however smirked as he looked down. "It's just us in here, no need to be all bashful." He cooed, kissing his cheek. "And I must say, you look so adorable like this."

"Aww... Thanks Kai."

Grinning, he rolled onto his round belly, shaking his booty at the flustered blonde. "You like what you see?"

"Oohoh, you never told me you were so dirty." Lloyd smirked, belly bumping his enormous butt. "Jiggles like a bowl of jello, I like that. You ready?"

"As ready as I'll ever be! Go long and hard Green ninja, think of it as your first lesson under the sheets."

Bouncing atop the older teen, Lloyd positioned himself. "Let's do this."

-------------------------------------------------------------------------------------------------

Loud moans and squeals emitted from their room, it bounced right off the walls of the cave. "What a time for them to start screwing." Jay grumbled, trying to cover his ears.

"Don't worry, when this place becomes fully functional I'll be sure to add soundproof walls to their room." Nya joked. "But on the bright side I did manage to scrounge up some info on the serpent that bit you."

Rolling over to the large screen in the center of the cave, Jay saw a golden yellow Serpentine with black stripes going down its back, frills down to the neck. But what caught his attention the most is how blobby it was, flab rolling down its scaly gut and its arms being much shorter and stubbier than any other snake they met. "The tester identified it was the Bogialtilis tribe, basically sumo snakes. Their venom flows through the victim's blood and expands them the more their heart rate goes up. Basically anything that excites or arouses you."

"Ah.. Umm, there's nothing about the victim..... Popping is there?"

"Nothing about that, don't worry. But nothing about how to deflate you either, maybe if you try slowing your heartrate through relaxation?"

"I guess that could work, or we could get that snake to come right over here so we can crush it!

Almost instantly a soft hissing came from the entrance. "Ah! It's found us!!"

"Shh, don't worry. I'll use the mech to deal with it." Nya assured to him, remotely sending her samurai mech to wrestle with the snake. "Boy it sure is putting up a fight!" She remarked.

But eventually the perpetrator behind the inflating ninja couldn't keep up and was grabbed. soft foam was forced onto the fangs to keep it from biting anyone else. "That ought to do it, now to create an antivenom."

------------------------------------------------------------------------------------------------

"So Mr or Miss Bogia.. Uhh.. Bogeyatlas.. No wait. What was it's name again?"

"Bogialtilis."

"Aw well I'm just gonna call it a Cobloat. You better deflate us right now!! I'm sick of bouncing everywhere!"

But the snake just smirked. "You boyssssss are sssssssstuck like thisssss, there'sssss nothing you can do."

"Stuck?! You mean we're like this for life?!"

"What? No, jussssssst for a couple dayssssss. Assssss long asss you don't excite yoursssssselvessss too much. Oh, my name issss Heliphat, not that it matterssss much." He grinned.

With that, he tail smacked Jay out of the way and squirmed through a tight pipe. "Aw great, so no video games or horror movies until we fully deflate?"

"Has anyone told Kai or Lloyd? I think they're still getting it on in there."

"... Oh crap!! Their room is gonna blow!"
