Most of those characters are not ones you can get as playable characters.
Can you get those characters without debugging it? If so, how? I want those characters but I don't want to mess around with mine. Thanks.
Those are 'visitors' only.
Like in Japan, the Dekka tamagotchi at Lotteria or the one at the Bandai office.
They are ones that you can only download.
They also give your other tamagotchis interesting gifts.
The Burgertchi guy gives hanburgers and fries when it visits another tamagotchi.
So by getting those characters on your debugged tama, it's like having a Dekka tama or the other company special tamagotchis.
Make any sense?
They are not really playable characters.
