Bloodgullet is invisible to you until you click on the Essence of Awakening, which is a pile of purple dust found in a hut at approximately 85.7,20.8 in the Ohn'ahran Plains (on the zone map, it's between the S and T in "TIMBERSTEP"). This gives you an hour-long buff that allows you to see Bloodgullet, who can be found wadering the meadows roughly south-east of the Maruukai flight point and north of the river (around 66.0,43.0).
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
