If all 3 were implemented, 2 of those 3 are Water prop, and if he was under Assumptio, that might be the reason. The "Miniboss" one would try to Suicide Bomb you at low health, so that's another one (lol Deepon).
Well, if the server REALLY updated, they're supposed to have their skills and property changes...so I'm really assuming that they've also let the mob variants walk around with the occasional "miniboss".
