There are 2 versions of the Tamagotchi Happy Meal Bags. I have scanned them both for my international friends who are not able to buy them. You can also make the Origamigotchi without cutting up your bags if you click here and print it out.
Version 1 has a maze on one side, and a list of 12
different characters, P1 and P2.
Version 2 has a code you must decipher to see the message
(In case you can't read it, it says "Take me to your
MILKSHAKE").
