you might. I is kinda random. You can almost any tamagotchi that fall in that type of caretakeing. YOu could just feed it more and give it snack(to boost up the happy hearts). Or play games with it to boost up happy hart and make it lose wight.
If you leave it with no happy hearts for too long it will get sick - and you'll need to cure it and give it at least one snack.
If you don't it will die and you'll lose your chance of getting the Gozarutchi... (btw - is it a V4 and male? - if so you have a chance of the Gozarutchi - if it's female you will have to wait for a male).
If it is a V3 it doesn't matter if it is male or female
Make sure the training is low. Gozarutchi is a near death experince tamagotchi. Just don't take of your tamagotchi that much. Ignore it most of the time..
