How do you make your tamagotchi a adult faster?

Question

Version 2 only, it's already 2 years old. and there is a code but i don't know where to put that code in.

Answer 1

I can tell you where  the code should go

if its alphabet's

go to the shop and click on the A 3 or 4 times until the shopkeeper look weird then press in the password

if its numbers go to the password place (you don't have to press on the A's this time just enter it the password and after you type in the last number press the middle button

Answer 2

Unfortunately, there aren't any codes for version 2. You can't make it grow faster for all versions. Bandai didn't make it that way.
