Angler Frog (5e Creature)
From D&D Wiki
medium beast, unaligned
Armor Class 11
Amphibious. The frog can breathe air and water.
Standing Leap. The frog can leap from standing position without a running start.
Hunts from Trees at Night. The frog generally hunts from the tree branches 15ft over its prey and does so by creeping up during the nighttime and tilting it's head all the way back to strike from above or at whatever angle is needed. Optionally, they also hunt prey that is in the trees. They are extremely stealthy and well camouflaged. A DC17 Perception check is needed to spot them in the trees (DC14 ground) and then the player sees the big bulbous eyes staring back at them. If the player scores 19 or more on the perception check, then they see the frog before it gets within tongue attack range. If the player does not make the DC then the frog gets a surprise attack. The Angler Frog is not very smart, but it will attempt to flee if there is commotion after it has secured a meal. If there is no commotion, it will sit and eat the meal right there.
Tongue Attack. Ranged Weapon Attack: +5 to hit, reach 15 ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage and the target is pulled immediately into the mouth of the frog and is considered grappled. If the target is tiny or smaller, it is immediately swallowed. Until the grapple ends, the target is restrained and the frog cannot attack another target. Roll a d6 to see if the tongue struck the face of the target. On a 1 or 2, the target's face is covered with hot, sticky tongue and it begins to suffocate. To make things simple, there are a flat 3 rounds of breath for the target. After those three rounds, there are rounds of struggle equal to the Constitution modifier of the grappled creature before the hit points drop to zero and the creature falls unconscious. To break the grapple, make a DC12 strength saving throw for medium creatures and DC14 strength saving throw for small creatures (because they are enveloped by the tongue and mouth). The frog is not very smart and may have eyes bigger than its stomach. Optional: Roll a d6. On a 1, the frog will randomly go for a target that is not small (or is not medium, if the party has no small members). If the frog hits a large-sized creature with a tongue attack, then it is pulled out of the tree and toward the target. This is the immense and reflexive strength of the Angler Frog's tongue.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage. If the attack is made against an adjacent creature, then it becomes grappled. If the creature is already grappled, then there is no roll to hit and the hit is automatic.
Swallow. Action: Swallowing is an action that is always taken after the Angler Frog grapples a small creature OR after a medium creature falls to zero hitpoints during the grapple. Upon being swallowed, suffocation begins if the target's face was not already covered by hot, sticky tongue. See Tongue Attack for suffocation rules. Death saving throws are automatic fails if the creature is both unconscious AND swallowed (only one fail per round). If the swallowed creature has a blade and is conscious, then it can use its action to make a DC15 strength saving throw to try to pierce the stomach lining. This is NOT an attack. The stomach is a very thick, mucus and acid-filled, vacuum-sealed bag of tissue that is very difficult to move against, and often the swallowed creature cannot turn the blade sideways enough or push hard enough to pierce this awful layer. Spell attacks are impossible to complete from within the stomach because of the extreme compression. After the stomach lining is cut, then both physical and spell attacks can be made against the frog from the inside (Bows are impossible to use, but an arrow or shuriken can be used as an improvised dagger). When making a melee attack as a swallowed creature, hits are automatic, but you must roll a d6. Non-dagger: on a 1 or 2 damage is dealt, on a 3 or 4 you cut your way out and it kills the frog, on a 5 or 6 you hit a vital organ and it kills the frog but you are still trapped until cut out. Dagger: on a 1-4 damage is dealt, on a 5 you cut out and it kills the frog, on a 6 you hit a vital organ and it kills the frog but you are still trapped until cut out. Spell attack results are gauged by the DM based upon the spell used. While you are inside the frog (whether the frog is alive or dead) you take 5 (2d4) stomach acid damage at the start of each of the frog's turns. The frog can swallow two tiny creatures, or one small creature, or one medium creature before it is full.
Of Note: While a creature is grappled, spell attacks that have an area of effect against the creature will also damage the grappled creature. The same goes for any attacks that aren't necessarily precise. This is at the DM's discretion. Cutting a swallowed creature out may also deal damage if the character conducting the "surgery" is not careful enough.
The Angler frog often travels in small groups but is occasionally solitary. The Angler Frog is as big as a pony but is nevertheless extremely stealthy and camouflaged in the browns and greens of the trees. Naturally, given its size, it can only travel among the trees that are big enough to support it. It usually goes for smallish prey, but will occasionally take on a larger meal, sometimes one that is too big.
