How do you get certain characters on 4U?

How can you get certain characters on Tama 4U? 

Is there certain thing you do to help get a certain character/personality?

This website has various guides on the 4U and 4U+ among other colour models. Look to the 4U growth chart for the requirements on how to get specific characters and to the post adult personality chart to see the criteria for each personality form. Even though this topic is old, I thought I might at least answer it for the benefit of anyone else. Just googling the tama model and "guide" or "growth chart" is usually all you need to come across this stuff. There are quite a few websites that host guides for current models and there's also Youtube tutorials as well. The beauty of the internet, really.
