How can I add troll emoji to another community?

Hey!

I noticed that meta.discourse have some cool emojies! (:troll: :dealwithit: :challengeaccepted: )

Is it possible to add these to another community? Is there a emoji pack?

Is it allowed to copy these emoji?

Sure, I found most of them on the INTERNETS anyway :wink:
