I read 30⚡70. That may or may not be 30410, 30/70, 30/10, 30470...
I have not noticed these numbers before. In the start screen of the event you can see them clearly. On the moving eggs it is hard to spot. Do not know if they were there from the beginning.
Since I have the same numbers, no, no hints for Paddy numbers.
My guess would be 3 04 70, as an expiration date, so the rabbit throws really old eggs at you.
