I picked Snatch for one of it's feats from here:
SRD:Snatch - D&D Wiki
It would take an enemy, grapple them with improved grab, breathe on them (no reflex save), and then fling them aside. This was more it's dragonlike aspect.
This idea went with the more thought of the pounce ability. Improved Grab, if i remember, doesn't give you all those extra perks, just allows you to not get an AoO when you grapple. Snatch would swap out for Weapon Focus. Call it a more tactile feat over Weapon Focus.
Improved Overrun:
SRD:Improved Overrun - D&D Wiki
More focus on pounce and bullrush. Snatch and Grab opponents, take them under like a gator and drown them.
It's a big critter, it'll bullrush the enemy knock others sides bite, grab, Dive deep.
Take out improved Critical for this.
Most monsters have a standard set of feats, I wanted to branch out into something else for this one.
Beyond that, this guy is done.
