Traits

False Appearance. If the rocking horse is motionless at the start of combat, it has advantage on its initiative roll. Moreover, if a creature hasn't observed the rocking horse move or act, that creature must succeed on a DC 18 Intelligence (Investigation) check to discern that the rocking horse is animate.

Flying Mount. The rocking horse can serve as a mount for a Medium or smaller creature and can fly only while mounted.

Unusual Nature. The rocking horse doesn't require air, food, drink, or sleep, and it regains no hit points or Hit Dice at the end of a long rest.

Actions

Head Butt. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit:3 (1d6) bludgeoning damage.
