tamagotchi plus color, seven happy symbols

Hi, i wonder first how to get the seven happy/lucky symbols on my tamagotchi plus color... i found a website who explain how to do but is not very clear!

also i guess my tamagotchi has to be adult for get those symbols?!

if someone know a good explanation ..

thankkkksss

Your character doesn't have to be an adult - you can begin collecting the stamps when your tamagotchi is young. This is because the symbols do not change depending on your character; they are the same for each new generation. While your character doesn't need to be an adult, it might become an adult while you wait to collect happy symbols as some symbols depend on the weather outside, or require you to buy expensive items (eg. telescope) from the shop.

Binary has a great TMGC+C guide here on Tamatalk where all of the happy symbols are explained. Here's the link to the happy signs part of the guide: https://www.tamatalk.com/IB/topic/157709-tmgcc-guide/?do=findComment&comment=2595344

Edit: your character can begin collecting happy signs at any age

And it's a good idea to start collecting them when your tamagotchi is young, because some take some time to be acquired without cheats.
