I should rather say: "Deadly when angered", but of course not too much, so they wont be *that* hard. I also think, that boss-like enemies that are hard to beat could fit the game. What about multiplayer raids with goal to kill single, but very big and powerfull monster? Best if players would have to take advantage of terrain modification to win. Good idea would be to create some enemies composed of many parts, that act separately, but also work together. An example: Giant golden statue with six arms, that do act separately, so down arms catch your clonks, and middle and upper arms throw stones at clonks that are further away?
