This was meant to be a “scenic” encounter – that is – the PCs see it and move on. But no, the bamboo folk ninja in my party was keen to talk to the birds via “speak with animals”. This triggered the gryphs. They swarmed the PC and laid eggs in him., which then hatched and flew away. The PCs then retreated. To this day the poor player is teased about “his babies” and that “somewhere out there are baby birds with your face”. Love how games can turn out.
