Well, not exactly SLOWLY... I think they already have, just like that. I don't like Lovelitchi and Melodytchi, but they aren't as bad as these new characters. Kiraritchi looks like a human and Yumemitchi looks like a dog. I can't stand dogs... ._. There are too many new characters becoming the mascots. The mascot is SUPPOSED to be Mametchi, but Tamagotchi is getting too girly. Yet I'm a girl and my favorite characters are Mametchi, Spacytchi, and Kuromametchi instead of popular girly characters. I do love Himespetchi though...If the mascot has to be a girl it might as well be her.
How important Yumemitchi and Kiriratchi are going to be rubs me the wrong way.. Even if I do find them really cute.
Hopefully, the introduction of these characters is smooth, and they slowly replace Lovelitchi and Meloditchi.
Here are some more pictures.
