Hi there Shadow!

The reason you're having some trouble finding what you're looking for is that themed offspring are not tracked by the search system. The 'themed' options in the drop down are for captured, tagged themed pets only (these are pets caught, or obtained, during festivals or through special means, that have a special purple 'name' on their profile, like my Sweet Kiss Luffox here. You'll notice he's a first generation sylesti and that in his genetics box there is purple writing stating the name of his theme.

Purebred themed offspring are any sylestis that are directly descended from parents of only that theme. Therefore, a purebred Haunted Depths ryori offspring would have parents that all trace back to first generation themed ryoris with with the purple tagged name 'Haunted Depths Ryori'. My Zolnixi, Buttercup is an example of a purebred Monarch Zolnixi offspring. If you go to her lineage and follow all of her parents back as far as possible, you will find that all of the starters of her line are tagged Monarch Zolnixis.

However, if a Haunted Depths Ryori is bred with a Zombie Ryori, for example, this would not be a purebred themed offspring. This would be a crossbreed. Now, there were some threads and groups that were interested in crossbreeds for a while, but these sylesties rarely have much value, and I have not seen any sort of market for them (just so you're aware going forward).

In any case, enjoy!

Hi. Offspring go for a lot lower than their tagged parents. It depends on how many visibles and carries the pet has. Everyone has their own pricing system.

For me I only sell pets that have visibles. For every visible I usually charge 5K. I don't count carries, and I don't sell pets without any visibles. Why? Because most people are interested in visibles.

For the more rare themed I charge around 10K per visible. Neither a zombie or a haunted depths ryori are rare so go with 5K per visible or 2.5k per carried. BUT really it's up to you. There's no wrong or right way of selling a pet.
