Clifford The Big Red Dog

Keen Hearing and Smell. Clifford has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. Clifford has advantage on an attack roll against a creature if at least one of Clifford's allies is within 15 feet of the creature and the ally isn't incapacitated.

Flame Camouflage. Clifford has advantage on Dexterity (Stealth) checks made to hide in volcano/mountain terrain.

Multiattack. Clifford makes two attacks: one with its bite and one with its tail. Clifford can't make both attacks against the same target.

Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: (4d12 + 7) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and Clifford can't bite another target.

Tail. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: (3d8 + 7) bludgeoning damage.

Heat Breath. (Recharge 5-6). Clifford exhales a blast of scorching wind in a 20-foot cone. Each creature in that area must make a DC 14 Dexterity saving throw, taking (6d8) fire damage on a failed save, or half as much damage on a successful one.

Fetch. If a rock or similar object is hurled at Clifford, Clifford can, with a successful DC 10 Dexterity saving throw, catch the object and take no bludgeoning damage from it.
