In general, that's a good point, but as far as known storyline has gone, Krekka's never really introduced himself. Nidhiki's done most of the speaking on Krekka's behalf. Comparing to humans doesn't necessarily work, as we don't know much about Krekka's species itself. If all member's of his species are as stupid as he is, or near so (Don't know that it's been mentioned at all really, the only thing known about them is they're labourers and lower class on Stelt), then they may not necessarily have adopted something like naming each other within their own kind. please no. we already have Skrall of the Skrall, and Makuta of the Makuta. Those are explained, and i'm fine with them, but no more, please >_>
