Yeah it's probably those things in the lawn. I think their might be more then one. One is on your normal base and I think their might be others on the goblin maps maybe. I've seen that thing on the village lawn pointed out before. It supposedly looks like a demon. But is this guy actually serious? If he is then that's just silly. If anyone's curious as to what I'm talking about look it up on YouTube.
EDIT: just looked into it a bit myself on YouTube. Some people think the thing at the top corner of the lawn has a demon their. People say it looks like the demon Baphomet which looks kind of like a goat.
