The sky was clear, littered with several clouds as the Tornado soared over Mobius under the pilot of Tails. Sonic stood on the top wing of the red biplane as he looked down at the ground below. "How’re things looking, buddy?" Sonic asked as Tails checked the Tornado’s radar.

"All clear!" The young fox affirmed with a satisfied expression. "No signs of Dr. Eggman or his Badniks." He recounted as Sonic let out a pleased laugh. "Perfect!" The blue hedgehog exclaimed as he felt the wind through his quills. "Nothing could get bet—"

"Wait!—" Tails interrupted as he saw a small dot appear on the radar. "—there’s something coming! Quickly!" He shouted over the wind as Sonic let out a curious hum. "Huh? Maybe it’s Egghead trying to—"

He was yet again interrupted when a blur flew past the Tornado, a single feather fluttering and landing on Sonic’s nose. "Huh?" He muttered and grabbed the feather off his nose. "Did you see that?" He asked as Tails nodded. "Yeah!" He answered. "That blur looked vaguely like a hedgehog!" He said.

"A hedgehog, hm?" Sonic hummed inquisitively. "Never seen a hedgehog with feathers instead of quills before." He said as Tails, again, nodded in agreement. "I don’t think this’ll be the last time we see them." Sonic said confidently.

(Several days later)

You relaxed on top a tree in Green Hill Zone, a gentle breeze blowing through your quills and ruffling the plumage on your back. It had been a while since you passed that red biplane with that Fox and Hedgehog on it, but it hasn’t left your mind. Why? You had no clue. You didn’t know them and—

—WHOOSH!

A harsh breeze blew past, nearly knocking you out of the tree as a blue and yellow blur zipped by before coming to a stop near the tree you were in.

"Any signs of that chaos emerald yet, buddy?" The blue hedgehog asked as the yellow fox looked at his tablet. "No, I haven’t been picking up on anything." He said back as the blue hedgehog sighed. "Man, those little buggers are getting harder and harder to find!" He commented with a laugh, his buddy laughing along while being oblivious to your presence above.

It was while they talked about the location of the aforementioned chaos emerald they were looking for, that you heard the sound of an engine approaching while the dup remained none the wiser.
