Hi When we got the green penguin we got a free character slot, will be the same this time?
Actually, when we received Green Penguin, we didn’t get an extra slot, we got it from a complete separate facebook event.
They sent the 2 rewards together to save time I guess, so unless something similar happens I really doubt we will get another slot this time, unfortunately.
