Strange beings both of and beyond the natural world, pixies have magic that occasionally favors them in strange ways. For example, one out of every 10 pixies exhibits an additional spell-like ability that it can use once per day (caster level 8th), usually baleful polymorph, beast shape II (Tiny creatures only), or even a powerful spell like irresistible dance. Alternatively, you can change the types of effects that pixie dust can have on arrows-as a general rule, these alternate effects should be mind-affecting effects. Confusion, fear, hideous laughter, and hypnotism are all good choices for variant pixie arrow powers. You should take care when assigning alternate powers to a pixie, though, since doing so can create a threat that far exceeds what their physical statistics (and relatively low CR) can logically support.
