Welcome back gift box?

Logged in a random mule, and got a box that gave me four tempest equips, a porcupine pet, a hyper teleport rock, ap + sp reset, and meso magnet item pouch and auto potion.

When did they start giving those out. o.o

EDIT:went through all my random mule accounts, and got 4 in total.

my friend got one as well, except his had a yeti pet.

its weird, because he has been playing his character for the past week but still got the box

There's been some discussion about it already:
