***Amphibious***. The frog can breathe air and water.
***Standing Leap***. The frog's long jump is up to 20 feet and its high jump is up to 10 feet, with or without a running start.
***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 target is [[restrained]], and the frog can't bite another target.
***Swallow***. The frog makes one bite attack against a Small or smaller target it is grappling. If the attack hits, the target is swallowed, and the grapple ends. The swallowed target is [[Blinded]] and [[restrained]], it has total cover against attacks and other effects outside the frog, and it takes 5 (2d4) acid damage at the start of each of the frog's turns. The frog can have only one target swallowed at a time.
If the frog dies, a swallowed creature is no longer [[restrained]] by it and can escape from the corpse using 5 feet of movement, exiting [[prone]].
