My idea for the perfect tama is Tamagotchi Waterchi!! You could take care of your very own body of water, starting from puddle to pond to lake to ocean!!!!!! And it never dies, either! And it should be in color and have the classic keychain, but blue! And the designs would be somewhat similar to an Oceangotchi. And Tamagotchis visit your body of water, such as Mametchi, Memetchi, Kutchipatchi, Makiko, etc. And how much they like it depends on whether or not you'll get the next cycle. So you'd have to check its stats, and for feeding, you put in a special water fertilize to keep it healthy, and for cleaning, you put in a non-harmful cleaning chemichal. To connect also helps whether you will get the next cycle. If your body of water is better than your friend's body of water, then your Waterchi goes on to the next cycle!!! Of course, visitors serve the same purpose. To turn it into a pond, though, you can see a human hand sprinkiling something into the puddle to turn it into a pond. So you don't have to start with a puddle!!!!! Neat idea, huh? There is also a friend record and disipline for when it splashes you (
) and game, which is basically you surfboard with it. And the classic attention icon.
