If you find yourself with one of the GOLD tams, watch the paint job. The gold isn't the actual shell color. The "Tamagotchi" name came off my other gold one. The gold is touchy and can get quite nasty looking after a while.
Same is true for ALL gold virtual pets I have come across.
I'm pretty sure this represents all of my Gen2 Tamagotchis and a couple of cool extras that aren't mine. :0)
Thanks to my generous friends who let me borrow things ;0) You know who you are and it sure is fun having friends like you. :0D
