Mastodon

Source Pathfinder Unchained pg. 244
As a big, dumb creature, the mastodon requires only a few adjustments despite its high CR.
Array: The mastodon uses the combatant array. The GM adjusts its ability modifiers to +9, +4, and –1 instead of +7, +4, and +3 to reflect its major emphasis on Strength and its poor Dexterity.
Creature Type: As an animal, the mastodon gains lowlight vision and a –4 Intelligence modifier. It increases its Fortitude and Will +saves from +10 to +12.
Size: Since it’s Huge, the mastodon reduces its touch AC to 13 and increases its flat-footed AC to 21. It also increases its CMB to 21 and its CMD to 30.
Options: The mastodon uses its combat option to gain improved combat maneuver (bull rush), which also adjusts its CMB to bull rush and its CMD against bull rush. It uses its any option for extra hit points, increasing its hp from 126 to 151.
Skills: Since it’s not very intelligent, the mastodon has master Perception but no other skills.
Damage: The mastodon uses the two natural attacks column for its attacks and damage. The two attacks have the same average damage value, but use different damage dice.
