hmmm there is definitely some misinformation here...
Dorotchi- Take as average care as possible, not too bad, not too good. This could result in a mix of characters, so don't give up!
Alien Tama- ??????? Who do you mean? OH WAIT! Do you mean Kiwitchi? I think you do. HES MY FAVORITE TAMA OF ALL!!! Okay, for Kiwitchi you must be on an odd generation. Take PERFECTO care of the baby, and hopefully you'll get Hitodetchi. Make sure you keep Hitodetchi exceedingly skinny. Here's the trick - while your home, taake awesome care, while you're at school - I know this might sound odd - don't pause it. You should get Kiwitchi.
Ichigotchi: must be an even generation. Take as perfect care possible of the child.
Androtchi- Must be even generation. Keep hungry hearts filled, but be forgetful of the happy hearts..
Gozarutchi- Exceedingly easy to get. Must be even generation. NEVER play games. Use snacks to make him happy.
Masktchi- Same as Gozarutchi but must be odd generation.
Hanatchi- must be odd generation. Exercise ALOT!!! Make sure he's at th minimum weight. Occasionaly leave him hungry.
Hope this helps!!
