Hippulbash, master guardian of the Nakkai Ruins, has a number of little reaverbots that also occupy its room. These are referred to as Hippulbash "Child" reaverbots, and the fact that they do bear a bit of resemblance to the "parent" leads one to wonder about the true nature of the reaverbots...

In any case, several of these reaverbots reside in the Hippulbash's pool, and they will leap high into the air in an attempt to block any form of attack which might be fired at it.

Additonally, Hippulbash fires round bombs from its arms. Though they do possess the classic reaverbot eye, it is uncertain whether they are considered reaverbots or merely ammunition.
