i would like worm like creatures like in terraria that behave like diggers or eater of worlds but look diffrent
But if this is in the game, don't be like terraria, because its was impossible to have a calm time in your house in the underworld or in the skyes ( On terraria they pass by everything in his front, even your house, your family, your npc and that's is annoying)
MOST DETAILED SUGGESTION EVER Sarcasm aside, I really hate worms in terraria, though mainly due to lack of good ways to kill them early on. I'm not quite sure how annoying or not they'd be in starbound.
