If the target is prone, the clawfoot can make one bite attack against it as a bonus action.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage.

Fear Screech. The Branchwatcher wails a piercing screech causing all creatures in a 30ft radius to roll a DC 14 Wisdom Saving Throw or be frightened for 1 minute it is immune to this effect if its a construct. Additionally; the targeted creatures can choose to fail the saving throw.
