Monster Manual II
Improved Grab (Ex): If a forest sloth hits an opponent that is at least one size category smaller than itself with both claw attacks, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity (grapple bonus +21). If it gets a hold, it transfers the opponent to its mouth as a free action and automatically hits with its bite attack in the same round. It can then try to swallow its prey in the next round. Alternatively, the forest sloth has the option to conduct the grapple normally, or simply use its jaws to hold the opponent (-20 penalty on grapple check, but the forest sloth is not considered grappled). In either case, each successful grapple check it makes during successive rounds automatically deals bite damage.
Swallow Whole (Ex): A forest sloth can swallow a creature that is at least two size categories smaller than itself by making a successful grapple check (grapple bonus +21), provided that the opponent is already in its mouth at the start of its turn. Once inside the sloth, the opponent takes 2d4+7 points of bludgeoning damage plus 1d8 points of acid damage per round from the sloth's gullet. A successful grapple check allows the swallowed creature to climb out of the gullet and return to the sloth's mouth, where another successful grapple check is needed to get free. Alternatively a swallowed creature can try to cut its way out with either claws or a light piercing or slashing weapon. Dealing at least 25 points of damage to the gullet (AC 20) in this way creates an opening large enough to permit escape. Once a single swallowed creature exits, muscular action closes the hole; thus, another swallowed opponent must cut its own way out. A Large forest sloth's gullet can hold 2 Small, 8 Tiny, or 32 Diminutive or smaller creatures.
Scent (Ex): A forest sloth can detect approaching enemies, sniff out hidden foes, and track by sense of smell.
Skills: A forest sloth receives a +4 racial bonus on Climb, Move Silently, and Spot checks when in forested areas.
The forest sloth typically attacks by leaping on prey with a frenzy of bite and claw attacks. Families of forest sloths often hunt together, using one as a scout to lure prey into the trees where the rest of the group waits in ambush.
