Let the countdown begin...

Foals please take care, please be aware;
all that you've done, will come to bear.
Have you been good? Behaved as you should?
Those who have not, it's understood;
Grogar will come, looking for some.
You are not safe, best that you run.
You're on his list, not what you wished.
This Hearth's Warming you will be missed.
