Making Zodiac pet

If you get all 12 Newborn Zodiac Pets, all 12 Adult Zodiac Pets, or all 12 Legendary Zodiac Pets, you can present yourself to Norah Kalesy to be rewarded with a Secret Zodiac Dragon Pet Summoning Stone (Stage 1, 2 or 3, respectively).
Buffs: U can stack up 3 buffs together summonig newborn, adult and leg. zodiac pet at the same time and having different buffs from your choice or having the same buff of your choice from adult and leg. zodiac pet.
Notes:
You must have all 12 of the same age to get the 13th, so if you want the Secret pet don't upgrade any of your pets until you have all 12 of that age.
You can keep them in your Partner Bag until you are ready, but will need to remove them from the bag when you want to do the turn-in. You will get them all back when he gives you the 13th.
Once you have raised your 12 Newborns, gotten the 13th, and start raising the 12 to Adulthood, you can then make another Newborn. In the end, you CAN have 39 pets, but at minimum you would have the original 12, now raised to Legendary rank, and the 3 Dragons.
