Much as I'd like the chance to catch some pygmy phoenixes myself I don't like the idea of flooding them again. The ones that were lost are going to be replaced so I don't think it's fair to add more of them. It'd just make it harder to get at other creatures you're looking to catch.

It's an approved idea, but I'd really rather they concentrate on replacing lost creatures and making whatever repairs and changes they need to than adding this right now. Whatever we report as missing will be replaced anyway.
