How do you use slaved bugs?

You use them in battles, if you you press battle button, you can in defense page add your defense, by pull their icon to defend surface, or passageway, or quens chamber. Important. If enemy defeat your creatures you don't lost them, you can only lost your soldier ants, if you attack, and also you can fuse them, to stronger them, but if it unsuccefull you lost one of two creature. Highter level= hingher power BUT higher change to lost fusion.
