It's a vaguely anthropomorphic yellow and green-furred creature resembles a cross between a monkey and a spider, with four spindly arms, bowed legs, vicious mandibles, and a crown of bead-like eyes around its head.

Dream Debt (Su) A bushyasta's bite places an insidious curse making the victim restless and insomniac on a failed Will saving throw (DC 15). The victims have to make another Will saving throw each time they sleep. On a failed saving throw their rest is disturbed and interrupted multiple times increasing their dream debt by 1 hour. The accumulated dream debt increases the number of hours the affected creatures have to spend to gain benefits of healthy 8-hour rest, including regaining spells and other abilities refreshed during rest. A successful break enchantment, dispel evil or remove curse ends the dream debt, though the hours of dream debt already accumulated have to be slept off. Heal and restoration spells remove accumulated dream debt but do not end the curse. Greater restoration ends the curse and erases the accumulated debt while lesser restoration removes 1d4 hours of a dream debt without ending the curse. The dream debt can also be ended by killing the bushyasta who caused it. The bushyasta can also dismiss it, though it will only do this when forced to or when coercing its victim into committing an evil act. This is a curse effect. The saving throw DC is Charisma-based.
Surreptitious Bite (Ex) A bushyasta biting a sleeping creature deals nonlethal damage without waking up the victim.
Bushyastas are spreaders of sloth, insomnia, and anxious dreams. Many of them prefer to haunt whole families and villages, sowing seeds of weakness to many, to undermine the community ability to function, while the others pick on single targets to turn their families and communities against them for perceived laziness.
Bushyastas' weakness is the smell of fresh tea, coffee, and similar stimulating herbs. They find it highly repulsive and they will avoid it, though they are likely to lash and try to spill any such beverage if it is prepared or presented within their reach.
A successful Knowledge (planes) check against DC of 21 allows recognition of the symptoms of the dream debt as result of a bushyasta's curse. If the check is exceeded by 10, the identity of the specific bushyasta that caused it can be determined. It can be then called with lesser planar binding and bargained with or forced to end the curse.
A typical bushyasta is 3 feet tall and weights around 40 pounds.
