Seahorse, Giant

Charge. If the seahorse moves at least 20 feet straight toward a target and then hits it with a Ram attack on the same turn, the target takes an extra 5 (2d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 12 STR save or be knocked prone.

Underwater Camouflage. The seahorse's Stealth is 19 while underwater.

Water Breathing. The seahorse can breathe only underwater.

Ram. _Melee Weapon Attack:_ +4 to hit, reach 5 ft., one target. _Hit:_ 7 (2d4+2) bludgeoning damage.

Grasping Tail. The seahorse grabs one Medium or smaller creature within 10 feet of it. The target must succeed on a DC 12 STR save or be grappled (escape DC 12). Until this grapple ends, the target is restrained, and the seahorse can't use Grasping Tail on another creature.
