Well i don't think that it's very smart to debug your tama. (no offense to any who thinks it's wonderful or something like that) It can wreck your tama forever
But yes debugging is a way to make your tama's grow faster
what i do is
i leave it at home during school and set the time to 10:00 PM...
actually you were right for most of it but
it takes 5 min for the egg to hatch into the baby
and 1 hour for the baby to grow into a toddler
(give or take a few minutes)
try treating it way differently
i had a ufotchi they're not all that bad.. i think they're cute
and my ufotchi turned out to be something cute.... a nyorotchi
(i know i hated my ufotchi at the time and i took really bad care of him so i got one)
i might be able to help you cause i have one currently
i had a teletchi (girl)>mizutamatchi>obotchi>pyonkotchi
i took very good care of him
and i keep his weight LOW!
