It seems I have caught all three of the Sinnoh Legendary Eggs! Unless there's more I haven't seen yet... :wipping:
A Porygon. Never seen one before so I caught it straight away (ya know, just in case it is rare or something).
Another Sinnoh Legendary Egg. I only now realized even as eggs that all look the same, the catcher will tell you if you have that particular one or not. So I should keep an eye out for Legendary/Mythical eggs I have not yet collected.
Riolu, since is one I don't see often I decided to catch an extra for later use of the living dex I'm trying to complete on LV.
