what are these pets from?

[organicbunny]

I've been going through my pets to sort them into groups by source, and I found 3 that I can't find in the Archive. They're all from 2024-12-18. Does anyone know what they are from?

By the way, please don't attempt to trade me for these. I want to keep them.

They are old pets that were re-released on 2024-12-18. Any pet with an adoption date on 12-18 is most likely a re-released pet. Their original archive dates are:

2009 Valentine's
2009 August
2015 Halloween
