This question should be on "Help for new pet owners"
but i'll help you
: On a v2 you must take good care of your toddler (child), make sure his/her discpline is high
Mametchi: Take good care of your tamagotchi and make sure your tamagotchi have high displcine. (Play game with her/her often) (Odd Generation)
Mimitchi: To get him you can do the same as Mametchi but you tamagotchi must be on a EVEN GENERATION.
Ok i just had Gozarutchi so i can tell u all about!:
Let him/her strave to almost to death!
Make sure he/she has very little discpline
make sure he/she is very fat
take a while to clean up his poop (clean it up after like 2 hours)
when he/she beeps ignore him/her
dont play much games with him
Simple isn't it
Be careful he/she doesn't die
I don't know about Chomametchi I just had him on the 7th generation
I never had Pyonkotchi but i think he/she appears on the Odd generation
