Gallimimus (5e Creature)
From D&D Wiki
Large beast, unaligned
Light Build. The gallimimus is considered to be a Medium animal for the purpose of determining its carrying capacity.
Trampling Charge. If the gallimimus moves at least 20 feet straight toward a creature and then hits it with a kick attack on the same turn, that target must succeed on a DC 14 Strength saving throw or be knocked prone. If the target is prone, the gallimimus can make another attack with its kick against it as a bonus action.
Multiattack. The gallimimus makes three kick attacks.
Kick. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage.
Peck. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.
The gallimimus is an herbivorous dinosaur, with very close relation to birds. These large, ostrich-like creatures travel in large flocks across open grasslands, pecking at seeds, plants, and insects on the ground. They can put up a decent fight, but their first instinct is usually to run.
