Or even have a port such as eeee said so we could plug a light into it AND plug it into our computer so we could download Mp3`s into it!Then we could have whatever song we want!!!...Or even a digital cam!!!{ok that is going a bit far but we can dream}
I think "Glow In The Dark" would be annoying at night time.....I like solid colour, I dont know why I just thing solid colours look nice I guess....But designs look nice also....
I voted for Heat-sensitive. It would be one of the easiest things to add, without getting rid of the current colors and designs. It also wouldn't increase the cost of a tama by very much, if it increased the cost at all.
I think all of those sound pretty cool, but I voted for the glow-in-the-dark one. I love those stars and stuff, and I would love a tamagotchi with stars on it.
