Bounding. A nandie-ape can make casual leaps of up to 10 feet as free actions when it moves. If a nandie-ape crosses broken terrain with obstacles it can climb or leap onto (boulders, tree limbs, roof beams, cage bars, et cetera), it moves at its climb speed and ignores difficult terrain caused by the obstacles.

Call to Arms. A nandie-ape boss can use its bonus action to make screeching calls. This gives it advantage on melee attack rolls against a creature if at least one of the nandie-ape's allies is within 5 feet of the creature and the ally isn't incapacitated.​

Multiattack. The nandie-ape boss makes two attacks: one with its bite and one with its claws.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) slashing damage.

Rock. Ranged Weapon Attack: +5 to hit, range 25/50 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage.
