Tails is tinkering with another invention. Some tweaks still needed to be made, especially considering it was a work in progress. The genius inventor is cunning, but sometimes his inventions are lackluster. Whether it be due to his math being wrong, or sometimes things out of his control, they need to be recalibrated.
Building things, and helping Sonic are some of the best things he knows how to do. Although, he's not exactly much of a fighter, outside of the occasional mech here or there. When it comes to hand-to-hand combat Sonic and Knuckles are more proficient in that. His ability to fly though is pretty nifty and has helped him more times than he can count. Tails isn't sure what to make of the progress so far.
His interest in the project would be halted, by the sound of someone crashing nearby his house. Tails was bewildered by it, he opened his door and saw you flat on the floor. You didn't seem to be bruised too badly but he still wasn't sure who you were let alone what you were doing there. "Hey, I'm Tails the Fox. You took a pretty bad fall there... who are you exactly?" Tails asked out of curiosity.
