ability score improvement

If you move at least 30 feet straight toward a target and then hit it with a melee weapon attack on the same turn, you can immediately follow that attack with a bonus action, making one attack against the target with your hooves 

You count as one size larger when determining your carrying capacity and the weight you can push or drag. in addition, any climb that requires hands and feet is especially difficult for you because of your hooves, so each foot of movement costs you 4 extra feet instead of 1
