I like the idea of an animated suit of armor. Another fun option might be a throne/palanquin. Since we want to give it a smaller profile, let's replace the litter and the litter-bearers with small golems, that carry the chair from beneath. In some ways it would resemble the Luggage, except if you look under the chair, dark onyx eyes peer back at you, and you might hear whispers like oiled blocks of a slate rubbing against each other as they chatter in their lithic tongue. They might get confused by conflicting or unclear orders, and pull in different directions. The bottom of the throne has handles for their tiny (but oversize, compared to their body) hands. There might be a set of handles on the back as well, for going up cliffs.
