I don't think hiding wires should be a problem. I'll hollow out one of the legs to run wires from the speaker & main board in the body to the batteries & switch on the base. Also... These came in the post today! Spoiler: Carno, 2 voice modules and MP3 player Speaker is way too big to fit inside the carno mouth, I'll get a smaller one. Time to test these out before I go buying that better one for a playlist of roars.
