Yeet. On a successful melee attack, Zak the Yak may attempt a grapple against the target as a bonus action. If the grapple succeeds, rather than become grappled, the target is flung up to 30 feet into the air and up to 10 feet horizontally in any direction. The target takes 1d6 magical bludgeoning damage for every 10 feet it falls from the apex of this trajectory.

Aerial Yeet. If Zak is flying when he uses his Yeet ability, the horizontal distance increases to 20 feet and he may choose to launch the target upward an additional 10 feet.

Pack Animal. Zak the Yak can carry up to 720 pounds, and can push, drag, or pull up to 1440 pounds, without reducing his speed.

Sturdy Flier. Zak's flying speed is not reduced when carrying a heavy load or rider in heavy armor.

Gore. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage.

Trampling Charge. If Zak moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, the target must make a DC 15 Strength saving throw. On a failed save, the target is knocked prone, and Zak can make one gore attack against it as a bonus action.
