(sorry I took so long to start answering again I've been studying for a test I had thought I had to take, but it's next week. so that's why I haven't been doing this lately.)

Challenge 1-

it's night time and they all are around a campfire to fit the settings. 

Bash: this should be fun >:) 

Pow: yeah >:) 

Slamm-oh: I like scary stories!

Smack: sure sounds fun.

Peter: uh oh, I don't know about this...

Archer Pastry: ok, who goes first to tell a story?

Sarah Slime: I don't know, I'm going to ask random generator on the computer.

Sarah Slime: Slamm-oh will be telling a story first.

Slamm-oh: there once was a white rabbit critter with beady red eyes, that a group of party crashers tried to fight but the rabbit would often come out of nowhere killing each of the party crashers one by one. this one guy tried hiding in a bush from the thing that's when he heard something approaching a bush and there the rabbit comes and attacks him. he was never heard of again. 

Bash: Rabbits are still not scary one-bit slamm-oh. 

Pow: yeah sorry dude.

Slamm-oh: that's what you say now until you see a rabbit with beady red eyes. 

Sarah Slime: the next to tell a scary story is Archer. 

Archer Pastry: oh great, I haven't thought of anything...

Bash: of course you haven't.

Archer Pastry: hey give me a break... wait I might know one...

Sarah Slime: tell it.

Archer Pastry: there were once two brothers

(this is a reference to IT chapter 1, but like in trolls when stories or retold like in trolly tales, it features characters from the trolls series as the characters from other series. The story is pictured as Bash as Bill and Archer as Georgie. they don't fit the characters that well but that's all I could think of. it was either that or I was going to reference Pet Sematary I don't know which would be better.)

Bash: hmm...

Archer Pastry: the youngest of the brothers wanted to play with his ok older brother's paper sailboats with him in the rain, but his older brother pretended to have a cold because he didn't want to go out in the rain. the older brother said the younger brother could play with boat as long as it doesn't get ruined.

Sarah Slime: I see where this is going... did you watch that movie last night or something.

Archer Pastry: maybe a little bit. 

Bash: what? what movie?

Archer Pastry: anyways so the younger brother went out in the rain and the boat sailed in the water but eventually ended up falling into the sewer...

Bash: how is this suppose to be scary again? 

Archer Pastry:  shush your mouth I ain't done bash!

Archer Pastry: the kid said "oh no, my bash is going to kill me!" when the boat fell down the sewer and looked for it in it. but he found something extremely weird in the sewer. there were glowing eyes in the sewer it was a worm dressed as a clown in it... The kid backed up from the sewer. 

(I think I saw somewhere that trolls the beat goes on Mr.dinkles dressed up as pennywise somewhere I don't know if it was canon or fan-art lol. so that's what I want with... I can't find the picture anywhere now so if anyone finds it can you do me a favor and link it to me.)

Bash: pfft a clown, clowns are not scary! also you're putting us in the story I knew it! also why you make us kids in this story? 

Archer Pastry: that's what you think, but not this clown. and yeah I put us as the characters so what. but this story is based on a movie I've seen which you haven't. 

Archer Pastry: the worm clown said "Hiya Archie" the kid stared at the clown confused on why there was one in there, to begin with. "what a nice boat... do you want it back?" the worm clown said. "Uhm, yes please..." the kid said. "you look like a nice boy, bet you have a lot of friends..."

Bash: snore.

Archer Pastry: ehm as I was saying, "three, but my brothers my best-est." the kid said. "oh where's he?" the worm clown said. "in bed, sick" the kid said. "I bet I could cheer him up I'll give him a balloon..." the worm clown said. "do you want a balloon too Archie?" the worm clown said. "I'm not supposed to take stuff from strangers..." the kid said. 

Pow: this clown guy is sketchy.

Bash: you're not actually afraid of it are you, Pow?

Pow: Nah...

Peter: I am, it's a worm...

Archer Pastry: anyways back to the story, "oh well I'm Dinklewise the dancing clown! Dinklewise meet Archie. Archie meet Dinklewise" the worm clown said. the kid giggles at what the worm clown said. "now we aren't strangers... are we?" Dinklewise said.

Bash: may I ask why you choose mammoth bait to be the clown?

Archer Pastry: biggie dressed him as pennywise Hairoween aka trolls Halloween last year because that's who Dinkles wanted to be as for Hairoween for some odd reason the only reason why I know is he showed me pictures and that's when I asked what's it from and he showed me the movie. one thing I learned is that worm looks creepy with a clown suit on...

Bash: I don't believe you...

Archer Pastry: biggie gave me a copy of the photo. *shows him the picture of Mr. dinkles as pennywise.*

Bash: ... who could have thought that worm could look so creepy and menching... 

Sarah Slime: Archer... your story?

Archer Pastry: oh yeah, back to where we were "what are doing in the sewer?" the kid said. "storm blew me away, blew the whole circus away *giggles.*" Dinklewise said "can you smell the circus Archie?" Dinklewise said.

Pow: yeah he probably does, like all the nastiness from the sewer... 

Slamm-oh: yeah lol. 

Archer Pastry: "peanuts, cotton candy, hot dogs and..." Dinklewise said. "popcorn?" the kid asked. "popcorn! *giggles* is that your favorite?" Dinklewise asked. "uh-huh" the kid said. "mine too *laughs* because they, pop, pop pop pop." Dinklewise said. 

Pow: no! Pow Pow Pow!

everyone stares at pow.

Pow: what? Pow is my favorite onomatopoeia word.

Peter: because it's your name...?

Pow: well yeah!

Archer Pastry: how many times you guys going to interrupt this story, anyways the kid giggles at what Dinklewise said about the popcorn. "pop pop pop" Dinklewise said. "Pop pop pop." the kid said. they both giggle about the word till Dinklewise stares kind of creepily making it silent now. "Uhm... I should get going now..." the kid said nervously. "oh, without your boat?... you said it yourself Archie, Bash's gonna kill you." Dinklewise said. "here, take it..." Dinklewise said. "take it archie..." Dinklewise said menacingly not seeming as friendly as before staring creepily at the kid. The kid reaches down to get the boat-

Bash: no don't be stupid! don't freaking take it!!!

Archer Pastry: Dinklewise opens his mouth to reveal several teeth.

Smack: like a baby country troll. 

Everyone but smack: shhh! it's the scary part smack!

Smack: ok sorry, jeez...

Archer Pastry: and Dinklewise chomped on the kid's arm ripping it off the dragged the kid into the sewers supposedly never to be seen again... 

(yeah I think I might have to turn this book rating from k+ to teen with the scariness and the gore mentions...) 

Bash: what the crash was that clown worm thing?!?

Archer Pastry: someone's scared... 

Bash: uh no... 

Peter: *sneaks the picture of Mr. Dinkles as pennywise creeping next to bash.*

Bash: *See the picture.* ahhhhhhhh!'

Archer Pastry: yeah, not scary.

Bash: it jumped scared me that's all... hmmpt I wasn't scared...

Archer Pastry: mhm...

Sarah Slime: the next person to tell a story is Pow

Pow: yes!

Pow: there once was a girl who had a doll, the girl's name was Powbelle. she called her doll powbelle as well and brought her everywhere...

(one of the Annabelle movies reference.) 

Bash: everyone is just going to insert themselves in the stories aren't they. 

Pow: then one-day powbelle died from getting trampled to death by mammoths, and her parents kept the doll.

Bash: ok that exalted quickly.

Pow: they though their daughter was haunting the doll, but really it was a demon. 

Peter: like you're not a demon already...

Pow: excuse me >:O

Peter: *laughs nervously* never mind, you're such a nice sister like an angel?...

Pow: I let you get by with that just this once, Peter pumpkin eater... 

Peter: peter pumpkin eater...?

Pow: anyways, the doll was possessed by a demon and she did such creepy things. it hurt the mom made her face disfigured from it attacking her. the dad locked it up never to be seen again, that is until the orphans came to visit.

Peter:  let me guess, they got the creepy doll from the closet.

Pow: yep and started possessing people and killing people, but soon the doll possessed one of the orphans and she's still out there with the doll looking to terrorize people. 

Peter: great now I'm scared of dolls.

Pow: that's why I burned mine, that and I was curious about how they'd look burnt!

Peter: *whispers to archer* I think my sisters a psychopath... 

Sarah Slime: well then aren't you creative Pow... ok the next person to tell a story is Bash.

Bash: so some teenagers were exploring a cave and they came across rock n trolls, and they hid and tried not to be seen. one dared one of the teenagers to walk into the room to see what the troll's reactions would be because rock n trolls tended to be rather brutal with intruders not to mention they had a rock golem guard called certain death that would kill intruders on sight.

Archer Pastry: certain death... sounds familiar... *remembers how he came across the rock creature called certain death when he and poppy got lost.* 

Bash: dad used to tell us this tale before he left, remember? every Halloween.

Archer Pastry: haha oh yeah right! that tale!... *thinks to self 'we were close to rock n troll territory 0.0'*

Bash: but certain death was the least of there worries compared to what an actual rock troll could do to them... the guy who got dared foolishly accepted the dare and walked into the room where the rock n trolls. his buddies were about to look at what was happening and heard a blood-curdling scream come from their friend and then it was silent... blood leaked through down to where the rock the others were hiding at scaring them at the sight of it... there was no way that their buddy survived the scary sight had them running as fast as they could out of the cave... their buddy never to be seen again... and that my friends is why I never have us crash Rock n Troll parties... even though rock n trolls have wicked cool style! but hey I heard even the bergens are afraid of them, that's saying something isn't? you know I wonder if we could ever have them as an ally one day possibly... 

Peter: King Thrash bit that guys head off didn't he, at least those are rumors I heard... anyways why were you so brave that time we came across the rock n trolls the one time?

Archer Pastry: you came across the rock n trolls?!?!

Bash: it was a rare sight ok? I wasn't thinking straight. it was just so cool to see them. 

Archer Pastry: they can't be that bad... I'm sure dad just heard rumors... you know trolls use to think party crashers eat trolls like bergens because we are slightly related to them, but we don't.

Bash: hmm true.

Peter: better safe than sorry, honestly...

Sarah Slime: ok next person to tell the story is Smack.

Smack: one day there was this guy who went in a ball pit.

Pow: Smack! ball pits are only scary to you! tell a different scary story!

Smack: well it's my story and I'll tell it how I want to tell it! thank you very much!

Pow: kay it's going to suck!

Smack: he went into a ball pit.

Pow: and drowned the end! ok Peter's next!

Smack: grrr... anyways he almost drowned in a ball pit. but he survived and held on to the edge of the ball bit... but then all of sudden he got dragged down into the ball pit by something! it was the creature of the ball pit! the creature dragged the guy down into the ball pit and he was never to be seen again... 

Pow: wow so scary, such wow...

Smack: whatever like your story about dolls was scary.

Pow: oh yes it was! wasn't it Peter? 

Peter: if I say no. you're going to prank me later aren't you...

Pow: hmm maybe...

Peter: yeah her doll story was scary.

Sarah Slime: the last person to tell a story is Peter.

Peter: so two parents and two kids moved into a house next to a mysterious pet Sematary... the girl kid had a pet swampkin. the swampkin died from getting trampled by a mammoth. 

(it's pet Sematary now guys, pow is Ellie in this story and I guess peter is gage but not a toddler?  IDK this based on the 2019 version. a swampkin is Churchill)

Pow: aw nooo! not the swampkin :'( I don't like this story, Peter!

Peter: her dad didn't have the heart to tell his daughter the swampkin is dead so he asked his neighbor what to do. the neighbor took him past the pet Sematary in the woods hearing odd and eerie noises as they travel. they arrive at an ancient burial grounds. the neighbor said to bury the cat here so he did. when the dad returned to the house the swampkin was back alive but not as sweet as it uses to be, sometimes dead is better.  the daughter was excited to see that the swampkin was still alive. yet the swampkin acted extremely mean now. 

Pow: but why I don't understand...

Peter: it was the girls birthday party and she saw her pet swampkin on the walking path of mammoths she rushed over there to try to get her cat to get away from there. the dad didn't notice his daughter about to get trampled by mammoths till it was too late. he ran to try to save her but it was too late she was gone. they had a funeral for her and everything.

Pow: this story is more sad than scary...

Peter: the dad decided he'd dig up her grave and bury her in the ancient burial grounds while his wife and son went to stay somewhere else. he was going to bring his daughter back from the dead...

Archer Pastry: the same burial ground that made the swampkin evil... man he's stupid... some things really are better dead has he not learned that?

Peter: he buried her in the burial grounds, and she in fact did come back but she, of course, was not her self. 'dad I hear the woods' she said. eventually, she ended up killing the neighbor. then she killed her mother that came to check on her. her dad then brought the mother back foolishly than the mother killed him and brought him back. the undead family slowly approached where the boy kid was in the car about opening the door the rest is left unknown... this teaches us some times dead really is better.

Pow: great now I'm going to have nightmares about me dying than coming back getting possessed and killing are whole family peter... thanks a lot!

Peter: hey it was scary, so it did its job. 

Sarah Slime: well thank you all... your stories were all so scary not gonna sleep tonight... 

Bash: sleep for the weak anyways.

Challenge 2-

Archer Pastry: ok *puts black paint around bash's sunglasses and leaves* *giggles*

Bash: *puts sunglasses on.* 

Archer Pastry: pow take bash's sunglasses.

Pow: hmm ok, but why?

Archer Pastry: you'll see *snickers*

Pow: *takes bash sunglasses revealing bash to have paint circles on his eyes* *tries not to laugh.*

Bash: hey pow why'd you do that? 

Archer Pastry: look in the mirror

Bash: *Sees himself in the mirror.* Did you put paint on my sunglasses kaboom?!?! 

Archer Pastry: yeah funny huh?

Bash: now have I got to get new sunglasses! grr...

Archer Pastry: wuh oh... *starts running.*

Bash: *chases after archer*

(I don't understand the last challenge.)
