Or catch a messy AP egg, put it in all the hatcheries, and let it die of sickness. *g* Sounds mean, but you wouldn't lose your slot that way, and could already breed the first holiday pair.

Or even faster, pick a CB egg from the other biomes and put it into all the hatcheries right away. Should die of sickness within an hour or so...

Btw, I just caught that one. I'm very pleased, but it will be difficult to breed a mate for him. Unless I catch a 2nd gen by sheer luck, it will take me one to two years. Wow.
