Ysoki

Ysoki can store up to 1 cubic foot of items weighing up to 1 bulk in total in their cheek pouches, and they can transfer a single object between hand and cheek as a swift action. A ysoki can disgorge the entire contents of his pouch onto the ground in his square as a move action that does not provoke an attack of opportunity.

Ysoki are scrappy and nimble even when the odds are against them. A ysoki can stand from prone as a swift action. Additionally, when off-kilter, a ysoki does not take the normal penalties to attacks or gain the flat-footed condition. When attempting an Acrobatics check to tumble through the space of an opponent at least one size category larger than himself, a ysoki receive a +5 racial bonus to the check.
