So.. mine went in.. does it come back or do i have to create n do it again? ^^;

It will come out in a day or so as a rift pet.

adding that if your pet is a species that has the riftborn color (here) it will change to that, if it's a species that isn't available in riftborn yet, it will come back as an experiment!

and thanks for the info! Now.. if only the steamworks pets could take this long xP
