Weregoat

Shapechanger. The weregoat can use its action to polymorph into a goat-humanoid hybrid or into a goat, or back into its true form, which is humanoid. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Ram (Goat or Hybrid Form Only). If the weregoat moves at least 10 feet straight toward a target and then hits it with its horns on the same turn, the target takes an extra 7 (2d6) slashing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.

Multiattack (Humanoid or Hybrid Form Only). The weregoat makes two attacks, only one of which can be with its horns.

Maul (Humanoid or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage.

Horns (Goat or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage. If the target is a humanoid, it must succeed on a DC 12 Constitution saving throw or be cursed with weregoat lycanthropy.
