• Animate Objects (Su): Once per round, a random object within 20 feet of the ravid animates as though by the spell animate objects cast by a 20th-level cleric. These objects defend the ravid to the best of their ability, but the ravid isn't intelligent enough to give them specific commands.

A swallowed creature can cut its way out by using a light slashing or piercing weapong to deal 25 points of damage to the remorhaz's gizzard (AC 20).

The remorhaz's interior can hold one Large, four Medium-size, sixteen Small, or sixty-four Tiny or smaller opponents.

If the roc achieves a hold, it can fly off with its prey and automatically make a bite attack each round in lieu of a claw attack. It can drop a snatched creature as a free action or use a standard action to fling it aside. A flung creature travels 90 feet and takes 9d6 points of damage.

• Strands (Ex): Most encounters with a roper begin when it fires its strong, sticky strands. The creature has six such members that can strike up to 50 feet away (no range increment). A single attack with a slashing weapon that deals at least 10 points of damage severs a strand (AC 20).
• Attach (Ex): If a roper hits with a strand attack, the strand latches onto the opponent's body. This deals no damage but draws the stuck opponent 10 feet closer each subsequent round (no attack of opportunity) unless that creature breaks free, which requires a successful Escape Artist check (DC 23) or Strength check (DC 19). The roper can draw in a creature within 10 feet of itself and bite with a +4 attack bonus, in that round.

• Rust (Ex): A rust monster that makes a successful touch attack with its antennae causes the target metal to corrode, falling to pieces and becoming useless immediately. The size of the object is immaterial-a full suit of armor rusts away as quickly as a sword. Magic armor and weapons, and other enchanted items made of metal, must succeed at a Reflex save (DC 20) or be dissolved. A metal weapon that deals damage to a rust monster also corrodes immediately. Wooden, stone, and other nonmetallic weapons are unaffected.
