I hope you enjoy digesting the refluxfrog, beautifully rendered by Hugo Solis (https://deviantart.com/butterfrog). See you tomorrow (or, uh, later today, depending on where you are) with another monster!
This creature looks like an enormous frog, but its body seems to be made entirely of liquid. Its mouth dribbles acid which scores the ground and, when the creature burps, it releases a small stream of sizzling liquid.

Acid Burn (Ex) A refluxfrog’s attacks inflict acid burn which works like the burn special attack, except it deals 1d6 points of acid damage to an affected creature at the start of the affected creature’s turn.
Acid Death (Ex) A refluxfrog explodes in a spray of fog that acts as an acid fog spell (caster level equals the refluxfrog’s HD). The fog immediately deals 2d6 points of acid damage to each creature and object in the area and at the refluxfrog’s initiative count in subsequent rounds.
Acid Reflux (Ex) Whenever a creature strikes a refluxfrog with a manufactured piercing or slashing weapon, the weapon takes 4d6 points of acid damage unless the attacker makes a DC 18 Reflex save. Damage caused to weapons in this manner is not halved, but hardness does help prevent some of the damage dealt. If a creature strikes a refluxfrog with a natural weapon that deals piercing or slashing damage, it takes 4d6 points of acid damage (DC 18 Reflex save for half). The save DCs are Constitution-based.
Breath Weapon (Ex) A refluxfrog can typically only use its breath weapon once per combat. For every 15 points of acid damage it deals with its swallow whole ability, it must use its breath weapon on its next turn. If a creature fails its Reflux save against the refluxfrog’s breath weapon, it is affected by the refluxfrog’s acid burn.
Refluxfrogs are unusual oozes that uniformly take the forms of gigantic frogs. This gives credence to the notion that the oozes were created by an intelligent race, but no explorers have turned up evidence of their manufacture. The frog motif is reinforced with their long tongues, formed from their membranous tissue. Rather than engulf their prey like most oozes, they use their tongues to pull prey into their masses as if they were frogs swallowing creatures they’ve ensnared. Refluxfrog bodies churn with acid, which becomes hyperactively productive when they consume prey. This forces the oozes to violently expel the acid moments after swallowing creatures.
Refluxfrogs stand 12 feet tall, are roughly 16 feet in diameter, and weigh 2,000 pounds.
