Will Goblins, Yetis, Sandworms will added? Or some ideas for new guys.                                                                                                                                                                                                                                                                                                                                              1. Goblin thief-Is a goblin with bandage, (What they will do?) He is hiding, and when he see ANY loot (Meat, wood, gold) He will jump and take all this things very fast, and start to run, (Where he will hide?) 1.Mini caves, its a rocks with a hole, you can rummage in there and find loot. Or find a thief :D.  2.Hollow's in trees. Same thing, but you can find only garbage, and rotten eggs)))). (How i can know where he is?) In these "holes" will sometimes appear eyes.                                                                                                                                                                                                                                                                                                                                                          2. Ogre Berserker.-Just a Ogre, but in armour, skull mask, and 2 hammers.                                                                                                                                                                                                                                                                                                                                            3. Cannibal's.-Its are people in In shabby and ragged gray clothes. Have white skin. Move's fast, but fears alot of people. Have black hair. Very thin. If they see human, they will attack him, and start eating his meat. They can eat mushroms, have a little health, but fast attack. How i say, they very scare the ALOT of people *4-6 man's* But if many people meet many cannibal's, they will start to fight without fear
