Mrs Busybody question

I have had Emmy and Colby playing together. Even though Colby is a bruit and gives her poo half the time, their friendship level is all 4 faces at the moment. I'm afraid to have them play again in fear of the faces turning into hearts meaning they're partners. Colby will not be an adult for another couple days and then he has to wait to mate. My fear is that Emmy will be too old to mate at that point. I want Mrs Busybody to come and give her a proper mate. She did come once earlier today but offered a Tarakotchi which is my least favorite character. She can do better. Will Mrs B come if she reaches a heart for Colby?

To be honest I don't know

I'm pretty sure she won't... But you don't have to worry about that, anyway.

Hearts can only be exchanged with adults. Teens can not gain hearts with other tamagotchis until they become an adult.
