I managed to run across the Christmas one (through cheating, of course; I was indeed too busy during Christmas with my family to play Tsukihime
- I went ahead and checked New Year's Eve too, to see if they'd pulled a Katamari Damacy on us, but no dice). Very cute, and good job to the staff for making us look extra hard
I haven't had any luck seeing the others, though... I know where
they're supposed to be located, but I can't seem to trigger them...
OOC, is this a case where I have to finish all the game routes before the eggs are accessible (like Insani's release of The Caged Vagrant), or something of that nature?
