Is this an annual thing, or is it just done whenever the staff are ready to bring it back? I can't seem to remember, all I know is that last time I didn't participate much, but I don't remember when last time was.

it used to be every year once in autumn, but one year it was also in spring.

It has been on hiatus since two years ago, when Achievements and the new battle system didn't agree. Now that the new battle system is fully in place and New Achievements are up, it's back.

- Alright, cool. Thanks for answering!

you are welcome. My pets are two year's worth of training stronger, so I'm expecting to kick some gelatin butt this time around.

- Yeah, my pet's a bit stronger now too. Not really strong, but I can probably get a few more defeats in now than I did last time anyway.
