They are just chill guys. They show up every night and leave christmas presents under the tree. Just don't interrupt them. lol but if you do try chasing them all out of your house and locking the doors but be nice to them or they might not be as friendly.
You killed one of them, didn't you? They gave you presents for free and you attacked them, and they did not take kindly to that. Don't harm any more and they may leave you alone eventually.
