Thanks to the articles on this wiki, I now have the necessary information to start making a growth chart for the Yasashii Tamagotch!
The info I have:
Good Care: ChikachikaBabytchi -> Hoppetchi -> Meruhetchi -> Oshamatchi (perfect care) / Jr. Mametchi (above average care) / Tamabetchi (average care) / Pantarotchi (below average care) / Jr. Ginjirotchi (bad care) / Micheltchi (VERY bad care)
Bad Care: ChikachikaBabytchi -> Hoppetchi -> Mayumarutchi -> Pantarotchi (perfect care) / Jr. Ginjirotchi (average care) / Micheltchi (bad care)
Special: Pantarotchi -> Kabuto Oyajitchi (perfect care)
