How long does it take sylesti to become adults? I could have sworn that they turned into adults at 21 days, but I have pets in my hatchery that are 22 days old and still are adolescents. I've raised soooo many sylesti but I've never paid attention to the exact date they turn into adults. I feel stupid having to ask this lol

with no/little amount of nurrituring it take 26 days for a pet to grow adult from a breeded egg, but it is realy more of a point things. All pets nead 248 points to turn adult every 4 (hatchi) or 6 (egg) nurriture, one point is added to it's maturity, they increass by 1 each hour and an adolescent can use a pie to increass it's maturity as well. To see how many maturity point a pet have, all you nead is to test it. ^-^

where'd you get 248 from? typo?

@Logei,
For a bred egg, they spend 72 hours (3 days) as an eggling (with every 6 correct nurtures speeding them up an hour)
Once they hatch (autohatch at 96 hours), they will be a hatchling. They spend 144 hours as a hatchling (6 days) and will hit adolescence at 216 hours (every 4 correct nurtures they will age up an extra hour) (the time they spend at '72 hours' waiting to hatch is added to their timer properly once they hatch, so if you have an egg that's been waiting to hatch for 12 hours, saying it's 72 hours old, will automatically update to 84 hours once you hatch it)
Once they hit 216 hours, they'll spend 432 hours (18 days) as an adolescent, until they hit adulthood at 648 hours (can be sped up via a max of two magical pies, each one skipping them 144 hours/6 days and with a 72 hour/3 day cooldown)

so
eggling = 3 days, hatchling = 6 days, adolescent = 18 days, so they hit adulthood at 27 days.

(oof, yea, big typo there lol, i was looking it up on oune of my adolescent and my dumb brain decided to pick the wrong time to space out ^-^')
