Thanks guys,
Yeah Im from the UK, we had some strange tamagotchis. I had a look at the Nano's and It was nothing like them

I do remember most things it did though. It was one of those odd multi pets that just kept evolving into different things I never really got very far with it I think it went:
blob => blob with tail => larger blob with tail => dog => monkey => caterpillar . . . .
I cant remember how many games there were but one was called rolling stone, where you rolled a stone at the pet and you had to press at the right time so that it jumped over it. When it was sunny you had to put a hat on it and it also had a punish button and a sound off button.
I had a tamagotchi connect at one point but never got on with it. If you know a pet that might be similar chip wise please let me know. Im considering getting a Yuki Pengin as they seem cute.
