ACTIONS
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6+1) piercing damage and the target is grappled (escape DC 11). Until this grapple ends, the frog can’t bite another target.
Swallow. The frog makes a bite attack against a Small or smaller creature it is grappling . If the attack hits and the frog has not swallowed another creature, the target is swallowed and the grapple ends. A swallowed creature has total cover from attacks from outside the frog, it is blinded and restrained , and it takes 5 (2d4) acid damage at the beginning of each of the frog’s turns. If the frog dies, the target is no longer swallowed.
Vaulting Leap. The frog jumps up to 10 feet horizontally and 5 feet vertically. If it’s within 5 feet of a creature that it is not grappling at the end of this movement, it may make a bite attack against that creature with advantage .
