Good Morning Sprinkles. xx

Sundays riddle answer was - Death.
********************************
Yesterdays again in case you missed it.

I’m an animal that jumps when I walk and sit when I stand. What am I?
******************************
Todays is:-

Joined at the beginning and then slung on your back.
Twelve brothers and me make one half of black.
Break any rule and you'll get instant removal.
Violence with me doesn't meet seal's approval.
What am I?

All answers on my back wall please xx
