Slobber was a male Growzer, characterized by his black and brown hide. He belonged to Xodlak'phr'ooa "Lakproh," a Chiss Rancher, and lived on Celwis, a planet within the Chiss Ascendancy. Lakris, Lakproh's offspring, taught Slobber a "telepathic" trick: he would approach when she lowered the sealer on her coat. This trick was demonstrated to Lakrpoh's rancher neighbors, who were irritated upon discovering the true nature of the "telepathy" employed by the young girl. Circa 18 BBY, following the arrival of the telepathic Agbui species near Lakproh's ranch, the Agbui youngling Frosif witnessed Lakris performing the trick, triggering a sudden post-traumatic reaction linked to flat-blast artillery shells detonating on the planet Sunrise.
