I don't really know whats the Advent calender or something x3. Its on the 18th off December, i thought O.o

The Advent Calendar is a Christmas event of ChickenSmoothie. Do you know those calendars filled with a chocolate for everyday of December than you can get? Well, think of that, but with pets. Every day in December, you go to the Advent page, and adopt the pets for that day.
On the 18th though, there is something special. For that day, there is a different box. You get two pets out of this box. When you adopt that that box you can get:

A 're-released' pet. A pet that was given out at some point in ChickenSmoothie history. They are usually good quality pets.
An 'unreleased' pet. Like the Tiger dog in your signature, pets that were never available for normal adoption.

Last year, a Malk Box was also available, which contained pets from Malk's various line arts. no word on whether it will be released again this year.
Hope this helped.
