the reason it isnt working is because when you first buy the plane ticket it doesnt give you the password right away you need to go to your items and it should be in there and you press b on it and it should go on a plane and then when it gets back it gives you a password i hope it works...
i dont know how l;ong the whole life is im guessing like 15 genarations
well once your tamagotchi is 4 it turns in to an adult
for me when its 7 years old at 3:00 pm
will once it gets married you stay with the baby for 2 days so its takes from9-11 days for a whole genaration
i hope its helpful
if you dont get anything dont collect them cause it doesnt make sence to spend hours just looking for suvineirs because you will get so in to it that once you get every one you will be thinking you get somthing but you dont so its like not even geting congradulated so thats why i wouldnt collect...
