Odd pets
Hitorikko pets
These are Dinkie style pets in that their outcomes are based largely on the food you feed it.
Versions of this include:
Dog, Dinosaur, chicken and fish!

I believe Hitorikko means something like 'only child'.
Love Chu and Love Chu2
For a short time, I had a pair of Gen1 Love Chus going along with a pair of Love Chu2's.
They are very much alike though the Love Chu2 is a better version. It's as though the company went back and designed the program to run a little better and more logically. The Love Chu2 is more intuitive in the way the game is played.
The game is just a repeat the move game but isn't nearly as obvious in the first generation.

These guys were pretty low maintenance. Just be there when they beep and they are usually pretty happy. Give them a bath after every meal too.  They look so peaceful in the tub!
I did NOT get them to mate. I'm not 100% sure about how that works. If you know, please let me know. ;o)
Cyber Pet Panda, Dog and Dinosaur.
I was very satisfied with these.  There are many games you can play.
It seemed easy to please and it was just so different!
The primary game is rock paper siscors but you can enter arcade style games too.  Games like car racing, tetris, pinball, Space Invaders and Frogger. Very nice!  The characters were also very nice. It was an interesting and easy going pet.
Uh, my pet Jeep?
I don't know what this one is. You keep it maintained and check on it's status.
It logs the miles it's driven.
It has an actual motor and the lights work and makes the usual car sounds.
I'm a car nut so this one was right up my alley. It's kind of a pet and it isn't.
