So, after watching the first Trolls movie a few times, just to have an idea of how Naruto becomes apart of it, I came up with this idea.

A Foxy Troll

Chapter 1

Pilot

Troll Village

It was an amazing day for the Trolls, they were singing their song about celebrating their freedom from the Bergens for the past 20 years, with each one having nothing but happiness for their freedoms, and not get eaten, along with Princess Poppy, who was leading the song, making it loud and proud for everyone to hear.

Though there was a slight problem, (clap(!), (clap(!), clap(!)) "Unbelievable guys(!) Really, really great, good job(!)" A Troll named Branch, with grey skin and black hair states, with sarcasm dripping from every word, "We could hear you from a mile away!" He soon stated seriously.

Unfortunately, Poppy didn't really catch the sarcasm, mostly because of how out of breath she was, "Good! I was worried we weren't projecting enough." Where she also missed the warning tone in Branch's voice.

Where another Troll walks up to them, with a deadpan expression, since he knows where this was going, this troll has orange skin, with red and yellow spiky hair, making it look like his head was on fire, along with bright blue eyes, with 3 lines on each of his cheeks, making him look like he has whiskers, wearing some red pants and white sleeveless trench coat with red flames on the bottom and a red spiral in the middle.

(A.N. Going for the Fourth Hokage robe, only instead of the "Fourth Fire Shadow" written in kanji on the back, it's gonna be an Uzumaki Spiral.)

This troll just happens to be Naruto, where he ended up in the Trolls world at the age of 9, due to how lonely he was, where at some point, he would sing to himself in his apartment just to try and forget his troubles and alleviate his loneliness, but because of how much emotion he put into his song, the fox that was sealed inside him at the time, decided to help out by sending Naruto to another world, where due to Naruto singing his heart out, he ended up in the Trolls Universe, along with becoming the Troll that he is today, where, at the time, he found a depressed kid-Branch, who had just lost his grandma to a Bergen.

After that, the two became adopted brothers to one another, with Naruto helping Branch with his depression, while Branch helps Naruto figure out how to be a Troll, but mostly, it allowed both boys to not be so lonely, since they now had each other to watch their backs, not to mention Branch's paranoia about the Burgans sometimes getting the best of him.

Which he had just mentioned, "If we could hear you, so can the Bergens!" Branch whispers at the end, causing the other group to moan at Branch's paranoia making its appearance, with the group telling him that he keeps on doing that.

With the twins stating, "You always ruin everything!" "Always warning us about the Bergens!" They stated after one another.

Though Branch doesn't believe them and simply replied, "No I don't, right Naruto." Looking towards his adopted brother.

Hearing the question, Naruto stiffened due to being put on the spot, where his mind thinks back to the times where Branch did do such things.

Flashback

As a clown Troll was giving a balloon to a girl troll, "THE BERGENS ARE COMING! AAAAAAAAAAAAAAAAAAAGH!" Branch yelled out, interrupting the moment with the two trolls, knocking the cake over and running away.

With Naruto chasing after him to try and calm him down, while yelling, "SORRY!"

2nd Flashback

As the clown Troll was giving a fork-full of wedding cake to the girl troll, obviously the two got married, "THE BERGENS ARE COMING! AAAAAAAAAAAAAAAAAAAGH!" Branch yelled out, interrupting the moment with the two trolls, knocking the cake over and running away.

With Naruto chasing after him to try and calm him down, while yelling, "SORRY!"

3rd Flashback

The clown Troll had passed on, with his wife having tears at the funeral, "THE BERGENS ARE COMING! AAAAAAAAAAAAAAAAAAAGH!" Branch yelled out, interrupting the moment, knocking the coffin over, which knocked the dead clown troll out of his coffin, with Branch running away.

With Naruto chasing after Branch, only this time he stopped in front of the widow and held the her hand in condolence, "I'm sorry for your lose, and for Branch." Then continued running after Branch to calm him down.

End Flashback

After such flashbacks, Naruto's face looked as though he didn't know how to answer that without upsetting anyone, including his brother, seeing as he has to live with him.

"Come on, we haven't seen a Bergen in 20 years, they're not gonna find us." Though luckily Poppy began talking, saving Naruto from answering Branch's tough question.

With Branch replying back, "No! They're not gonna find US! Because we'll be in our highly camouflaged, heavily fortified Bergen-proof survival bunker." Since even Naruto would admit that Branch was going a "little" bit crazy with the paranoia, but he can't really complain since it was perfectly safe from such a thing.

Though Poppy was upset, "You mean you're both not coming to the party tonight!?" Causing her group to moan about the pair not accepting the invite.

With each one stating, ""But it's gonna be the biggest,"", "the loudest!", "the craziest party EVER!" With the group yelling and agreeing with such a party.

Unfortunately, this didn't sit well with Branch, or Naruto for that matter, ""Big, loud, crazy!" You're just gonna lead the Bergens right to us!" Branch stated.

Soon Naruto spoke up, "Ye~ah, no offence Poppy, but I'm with Branch on this one, since it sounds like trouble to have such a large party that anyone could spot from a distance." The group was surprised that Naruto had agreed with Branch right now, since he was the most level-headed of the two brothers, he had a better understanding of Branch and can be quite reasonable, making the others think things over.

Unfortunately, Poppy wasn't really listening and still wanted to invite the brothers to the party, though Branch, after being "doused" by glitter from Poppy's invite card, took it, then crushed it under his foot, showing that he didn't want to go to the party.

Though, before things could go too far, the groups wristbands dinged, showing that it was "hug time" for them, with Naruto and Branch being dragged into the hug, but quickly forced their way out, since for Naruto, it wasn't really the right time for hugging, as for Branch, he wasn't really the hugging type, where the two brothers walk away from the group.

Night Time

Soon the part was in full swing, all the Trolls were smashing the party up and enjoying themselves, though in the distance Branch and Naruto were watching the scene, with Branch scoffing off the party, knowing that a Bergen would appear, with Naruto shaking his head and sighs, "Well, I tried to warn them."

With Branch nodding, until he looks towards Naruto sharply, "Don't you mean WE tried to warn them?"

Naruto just shrugs his shoulders, "Not really, since I'm the more reasonable of us both."

Hearing this, Branch gave Naruto and upset look and walked away, with Naruto following him, though after thinking about it, Branch can agree that he may have thrown a "few" yells about the Bergens, causing the others to not believe him, but he wouldn't say Naruto was right.

So with that, the party continued while Naruto and Branch sorted the bunker out.

Though as Poppy and her group had stated, the party was the biggest, the loudest, most craziest party ever, that they didn't realise that they were about to gain an unexpected "guest" that they didn't want.

The End.

There you have it, a Naruto/Trolls Crossover, with Naruto becoming a Troll himself due to singing his heart out and ending up in the Trolls Universe at 9 years old.

As for pairing(s) it'll have to be Branch/Poppy, for obvious reasons, while Naruto ends up with possibly Queen Barb due to his "wild" looks, though it be up to whoever adopts how they want the story, and pairing to go.

I Do Not Own Naruto Or Trolls.
