Next to Croak - RSP Encounter

In this encounter, the PCs are attacked by the bullyug berserker Gollup. She leads a pack of intemperate giant toads and wears a bandoleer filled with restrained poisonous frogs, which she uses as sling “stones.”
Have the PCs make a Perception check before reading:

A warble of croaking echoes through the swamp, sending stark white wading birds scattering like dandelion seeds in a summer zephyr. The croaking quickly rises in volume, drowning out the avian cries of alarm.

The PCs have one round to prepare for battle for every 5 points by which their highest Perception check beats DC 15. If none of the PCs make a DC 15 Perception check, Gollup achieves surprise.

Area Features

Trail: A 10 ft. wide trail wends through the swamp. On the trail, movement is without penalty. Bogs: Shallow bogs surround the battle site. It costs 2 squares of movement to move into such squares and the DC of Acrobatics checks increases by 2. Bogs increase the DC of Stealth checks by 2. Massive Mangroves: Huge trees tower above the bog. These huge trees (AC 3, hardness 5, hp 600; DC 15 Climb check) fill an entire square. They provide cover (+4 AC, +2 Reflex saves)

Tactics

As soon as Gollup spies the PCs, she challenges them with her terrifying croak (her companion beasts have already been affected by this today and are thus immune) and releases her wart-ridden pack, which gleefully pounce on the PCs. While the PCs fight her toads, Gollup hurls poisonous frogs at spellcasters and other unarmored opponents, causing each diminutive amphibian to bite their target for 2d4 rounds before fleeing. When either her toads are slain or she runs out of poisonous frog, Gollup charges into combat with her longspear, using Step Up and her sticky tongue to stop foes escaping.

Gollup

Gollup is a vile wanderer who scours the marshes and swamps for victims to torture and eat.
Background: Gollup is an exile from her village, banished for not returning from her coming-of-age hunt with a humanoid victim. Despite killing over a dozen elves and humans during the hunt, Gollup’s devoured each of them in a ravenous delirium born of one too many licks of a wartoad.
Personality: Gollup is brutish and crude, enjoying violence for its own sake. Her actions are driven by whatever base motivation flits across her mind at any particular moment. She is addicted to toad poison and is barely coherent.
Mannerisms: Gollup, as a result of her substance abuse, bursts into high-pitched uncontrollable laughter at irregular intervals.
Distinguishing Features: Gollup has horribly red, bloodshot eyes, which struggle to focus on the task at hand. Her dark, warty skin is dry and covered in fist-sized warts.
Development: If Gollup is freed of her addiction and toad-fuelled psychosis (perhaps with remove disease or heal), her attitude becomes indifferent, and she may be befriended with a DC 17 Diplomacy check.

Rage (7 rounds)
Sticky Tongue: A creature hit by Gollup's tongue attack cannot move more than 10 feet away from her and takes a –2 penalty to AC as long as the tongue is attached. The tongue can be removed by making an opposed Strength check as a standard action or by dealing 2 points of slashing damage to the tongue (AC 11, damage does not reduce Gollup’s actual hit points). Gollup cannot move more than 10 feet away from the target, but can release her tongue as a free action.
Terrifying Croak (DC 15) Gollup can emit a loud and horrifying croak. Any non-bullywug creature within 30 feet of her must make a DC 15 Will save or become shaken for 1d4 rounds. Creatures that succeed at this save cannot be affected again by Gollup’s croak for 24 hours. Creatures that are already shaken become frightened for 1d4 rounds instead.
Combat Gear - Potions of eagle’s splendor (2), poisonous frogs wrapped carefully in leaves (8), sling bullets (10)

Potion of Eagle's Splendor - For four hours, this spell grants a +4 enhancement bonus to Charisma (for a total of a +2 modifier), adding the usual benefits to Charisma-based skill checks and other uses of the Charisma modifier, such as bluff, intimidate, diplomacy, etc. Bards, paladins, and sorcerers (and other spellcasters who rely on Charisma) affected by this spell do not gain any additional bonus spells for the increased Charisma, but the save DCs for spells they cast while under this spell’s effect do increase.

Grab - If it hits a Small or smaller target with its bite, the giant war toad can try to grapple without provoking attacks of opportunity.
Swallow Whole - If the giant war toad begins its turn with a target grappled in its mouth it can attempt to pin the target. If it succeeds, it swallows its opponent (who takes [roll1d6+2] damage from its bite). The giant war toad loses the grappled condition, but its opponent does not. Every round, the opponent takes 1d4 bludgeoning damage. A swallowed creature can cut its way out with a light slashing or piercing weapon (AC 10, hp 1) or can attempt a grapple check to get back into the giant war toad’s mouth (where it can be bitten and swallowed again). If the opponent cuts its way out, the giant war toad cannot use swallow whole again until it has healed the damage.

Actions

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 1d10+2) piercing damage plus 5 1d10 poison damage, and the target is grappled (escape DC 13). Until this grapple ends, the target is restrained, and the toad can't bite another target.
Swallow. The toad makes one bite attack against a Medium 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 toad, and it takes 10 3d6 acid damage at the start of each of the toad's turns. The toad can have only one target swallowed at a time. If the toad dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 5 feet of movement, exiting prone.

This pit bull-sized amphibian is covered in hideous warts and ears a leather coat studded with sharpened bones and teeth. Its dark brown skin oozes a thick, white excretion.
