This topic sounds interesting!
If I was a tamagotchi, I would have a look kind like Himespetchi, except her unique style which I don't. Anyways, I would have brown eyes instead, and let my long, scruffy hair on my back. I would wear purple/black glasses and some pins on my right bands. I would wear a furry zip-on sweater, because I like wearing them, and some brown suave boots.
And that's how I would look but my personality would be different. I would just be more of a quiet and nice tama than just being unique. And I would love to have a pet that looks like a fuzzy duck if I was a familitchi version. :3
Plus I would be called Fukatchi since I like the word "Fuka".
