Hia guys! It's been a while! Got a little busy for a while there- but I've been working on somethings that I'm excited to be posting soon enough. I just wrote this in one go, so I hope there's not too many mistakes lol

As always, I do not own any of the characters!
Also, the ages vary from chapter to chapter, but do not matter much! In this one, I was thinking of them at the ages of 6 and 13.

Anyways, enjoy!

Tails, despite being a kid, doesn't always act like a kid. In fact, as he got a little older, it happened less and less. The kid was a genius, and often spent a lot of time working on planes or other inventions rather than doing kid-things and spending his days like a child should. Not that Sonic could talk; having been fighting Eggman since he was 10, but even the hedgehog knew when to chill out and often spent a lot of time having fun.

Tails instead spent most of the day cooped up in his workshop, building things that no other child could possibly think of. There were still times Sonic saw him acting his age, though, even if rare.

At one point, the hedgehog and fox duo were traversing over a very quiet, snowy zone. It was quite cold, but the sun was out, just enough to warm them as they trudged on, following Eggman's trail. After moving up a hill that was a bit icy and hard to climb, it seemed the lower valley in front of them on the other side was filled with deep, fluffy snow.

The deeper parts of the snow made Sonic wary; there could be a badnik ready to pop out at them- but so far, none of the bots they'd seen had utilized such a thing, mostly popping out of rocks or thin snow-covered dirt rather than big snow piles themselves.

Tails seemed strangely happy upon seeing the deeper snow, which was not in many places they'd walked so far, likely due to the sun melting it. There was mostly just a thin layer of snow everywhere. "Look, Sonic! That's fresh deep snow," Just as he prepared to jump into the snow, Sonic warned him.

"Careful Tails, I think there might be a bot or two in that deep snow."

Tails flicked an ear and looked back at him, and grinned. "I don't think so, they haven't been in any deeper snow so far, and I don't think Eggman would have calculated the weather far enough ahead to know when the snow would be deep enough to hide one. Plus, it's all fresh anyway, like I said. If he tried to hide anything, it would have left a mark."

"Oh, yeah? He's done crazier things to make a trap, though." Sonic replied, trying not to think too hard on the details of what the younger said.

The kit pressed one foot down into the deeper spot, allowing it to come up to his knee. "I think I'd be able to hear them anyway!"

"Why is that?" Sonic stepped in after him, a little more cautious yet.

It was a little strange(but welcome) to see the uplifting mood from the fox, who had been more than a bit down this time around since just earlier, Eggman had successfully dragged the Tornado down through a projectile hitting it's engine.

Though Tails had managed to pull the plane safely down to the land, they were forced to leave it there for the moment to chase after Eggman and his latest schemes. Which was another attempt at collecting the chaos emeralds, and likely something bigger as well. Tails loved taking care of the Tornado, and to see it in such rough shape definitely put him in a more sour mood so far.

The twin-tail swiveled his ears around separately, not answering, and then swiveled like a chameleon's eyes when they see their prey. He crouched down slightly into the deep snow, sticking his tongue out. Sonic smiled, realizing from experience that Tails was going to pounce forward.

Just as expected, he sprung up, quite high, tails swirling together. When coming down, he went face first, into the deeper snow, effectively leaving his legs and tails up in the air.

Sonic couldn't help it when he barked out a laugh. The sight was actually surprising; though he'd seen Tails pounce before, on himself and others, he hadn't seen the kit land like that, stuck in the snow.

With a little bit of struggling, and tails flailing in effort, he pulled himself back out, ears swiveling and he seemed a little confused. "Strange, I thought there was something here." Sonic laughed some more, amused. It was nice to see the kid act like, well, a kid, once in a while. "What'd you think was down there?"

Smiling, Tails replied. "I dunno, I thought I heard something under the snow. Like a squirrel, or something."

"You can hear things under that?"

"Yeah!" With that, Tails shifted back down into the snow, and instead of getting stuck, he effectively went completely under, though the movement of the snow made him look something like a mole digging a tunnel.

Sonic took a few steps forward into the deeper snow after the snow-digging fox. "You trying to be a mole, little buddy?"

Instead of giving a reply, the tunnel shifted in direction, turning around and heading towards Sonic quickly, and then Tails launched straight out and at him.

Hindered by the deep snow, Sonic only managed to stumble back with a "Woah!" when he got a face full of orange and white fox fur. Tails grabbed onto him, and they both fell back into the snow with a shout. Sonic was thankful now for it being there, because otherwise the fall may have hurt his tail or quills from the way they'd landed.

Tails giggled pressing Sonic down further into the snow as he shifted further down, off Sonic's face and more on the hedgehog's stomach instead. His tails twirled behind him playfully. "Got you!"

"Well you better move before I get you!" Thinking quick, Sonic reached out to snatch the kit's sides, a tickle attack that the kit recognized as he squeaked in alarm, just barely dodging the older's hands and taking another dive into the snow.

"You'll have to catch me!" He yipped as he began tunneling again with a laugh. Tails could have easily begun flying, but might have already reasoned that there was no high point to land on to be safe from Sonic, so going under the snow was probably a safer bet.

Taking the challenge, Sonic began revving up in place, and taking off right through the snow. It was a little harder to do than normal, but when you're the fastest thing alive, anything's possible.

Tails peeked up through the snow just in time to see the hedgehog racing towards him, and yelped, obviously thinking the other would be more hindered by the snow. "Wait, that's not fair!"

"All's fair, little bro!" The speedster responded with a grin, coming just close enough that he could lunge out. The fox dived under the snow just in time, and seemed to go into a deep enough area that Sonic wasn't able to grab him right away, as the snow crashed after the quick escapee, effectively cutting off his tunnel from where he'd entered back in.

Sonic stood still, then, watching the snow. They'd moved into a deeper part in the few seconds of chase, and it seemed that Tails was able to dig through the snow without it being too obvious on the surface.

Abruptly, with a cry, Tails came bursting out of the snow behind him, throwing snow everywhere and landing on Sonic once more. With luck, or maybe practice, he managed to not land on the hedgehog's quills, and instead wiggled into the space between his shoulder blades. "Got you again!"

Sonic reached behind him in an instant, trying to grab at the fluffy opponent. "Why, you!" He replied in a playful tone. It seemed Tails was up to playing right now, which was fine- he'd rather that than staying sad over the plane which would be fixed later. "Come here, you little mole!"

"Mole?" Tails giggled, masterfully dodging the prying hands trying to grab him by shifting between the quills on the older's back. "I'm a fox, Sonic!"

"But you sure look like one digging in the snow like that," Sonic teased, finally managing to grab a handful of the vulpine's fur. The owner yipped, and held tight, but eventually gave way and fell off of the hedgehog's back, back into the snow. Sonic's grip slipped from the odd angle, and let the kit escape once more.

Turning around to look at him, Sonic was just in time to see the kit spring up and once again land head first into the snow a little ways away, shoes kicking the air. Sonic snorted, and shifted through the snow fast enough that he grabbed one of the kit's feet and pulled him back up out of the snow.

Big blue eyes looked up at him, shocked. Sonic stared back, for a moment, and then they both deflated into laughter. "Alright, alright," Sonic spoke, dropping the kit down onto his back. "Let's keep moving! I bet there's gonna be another emerald here soon, I can feel it!" He decided that it was enough play for now, otherwise Eggman would get to the emerald before they did, and take it for himself.

"Okay, Sonic!" Mood lifted by his own doing, the kit bounced happily over the deep snow and onward in the direction they were heading. Sonic raced after him, overtaking to lead, sending snow flying everywhere.

Like the title / summary says there's going to be 6 chapters for this! Hopefully I'll be able to finish it all and it's not too horrible to read

Hope you enjoyed reading!
