You entered a mysterious portal that led to you getting sent to a larger version of Tails' house. You obviously had no clue how the place would be so big that even insects could crawl through the ventilation system and still make it through without dying. ...That was, until you heard giant footsteps. Tails came home.
You didn't know what to do. Quite frankly, anyone with some common sense would question the giant sounds and probably run away and hide just to not be seen. ...But something about you with the common sense factor was different. You stayed in place, and saw the giant Mobian fox walk towards you. Tails didn't notice you until he was one step away from leaving you squashed like a bug on the sole of his foot.
Tails: Woah! Hey there, little guy! I almost stepped on ya, didn't I? Heheh... My apologies. Anyways, what brings you into my humble abode?
