What are the methods to get the different characters in TMP1 and 2?
And also, do the "Oldie" characters only come on TMP4? Or do they appear on all TMP levels?

Hi Gotchi Gotchi. =]
I believe you already have, but incase you haven't, you should probably take a look at these charts by both binary and OsuMesu21; http://tama-zone.com/index.php?showtopic=14568 and http://tama-zone.com/index.php?showtopic=690. I believe that they will answer your questions.

Oh, and from what I know you can only get the Oldies in TMP4. =]

I already had read them but as it seems, not very well... the oldies only appear on TMP4 after perfect care and no mating, so that's that question answered...
So I guess, after i reread those charts, the characters closer to the top of the chart are higher care?
And what TMP1 characters you have affects what line of growth you'll obtain in TMP2.
But how *much* neglect do I give TMP1 characters to get the ones I want? Like, if I wanted to get Megatchi and Gankotchi, how much neglect is needed to get them? I'm afraind I'll give them too much neglect, and I'll end up with Sutebotchi and Tsuketchi.
