Gargantuan Presence. A Yu' Lompah's long neck rises high above any Huge or smaller creature, with an average length of 30 feet for a fully grown adult. It also has a long tail that extends a roughly equal distance when fully lengthened. As a result, Yu' Lompah have a Gargantuan size when determining height, space, and natural reach. Yu' Lompah also cannot be Grappled by non-magical means. 

Natural Balance. By manipulating their long necks and tails, and with the help of their giant wings, Yu' Lompah have a naturally strengthened center of balance. As a result, they gain advantage against being knocked prone. 

Bite.  Melee Weapon Attack: +4 to hit, reach 30 ft., one target. Hit:  7 (2d6 + 2) piercing damage.

Tail. Melee Weapon Attack: +4 to hit, reach 30 ft., one target, or any creature/structure standing within reach behind the Yu' Lompah. Hit: 9 (2d8 + 2) bludgeoning damage. Target(s) must succeed on a DC 12 Strength saving throw or be knocked prone.

Wing Attack. The Yu' Lompah beats its wings. Each creature within 10 feet of the Yu' Lompah must succeed on a DC 12 Dexterity saving throw or take 8 (2d6 + 4) bludgeoning damage and be knocked prone.

Bucking Giant. Whenever a Yu' Lompah is Frightened, the creature frantically flaps its wings, rising up on its tail like a bucking horse. Any creatures standing within 10 feet of the Yu' Lompah must succeed on a DC 12 Dexterity saving throw or be knocked prone. 

On the Yu' Lompah's next turn, its two front legs return to the ground with a quaking force. Any creature still prone as a result of Bucking Giant must succeed on a DC 12 Dexterity saving throw or they take 11 (3d6 + 4) bludgeoning damage and are stunned.
