Uhm, I logged on from a LONG break of not playing and in my Cash Shop I got..
Two 90 Day Jr Reapers
Two 90 Day Dino Girls
Two Permanent White Tigers
One 5 Day Snail
I highly doubt it's an event, but more of a glitch instead.. not that I'm complaining!
Kinda cool, but useless to me since I don't wanna buy that dumb Multi-Pet thing..
