Butterfrogs provide ingredients for many concoctions and magic items. Poison is the most obvious material a character can obtain from the butterfrog and its crossbreeds. A competent alchemist can gather saliva or skin secretions from a butterfrog or a crossbreed; the collected poison retains its potency for a day. A butterfrog's feelers provide an abundant source of ingredients for magic items, potions, and alchemical mutagens, typically those that enhance the senses or allow the user to change his physiology. Unscrupulous individuals kill butterfrogs, dissecting and harvesting the remains: the wings for items that grant flight, carapaces and scales for items that improve natural armor, and vocal cords for mind-affecting items. For those interested in capturing a butterfrog and able to withstand the onslaught of ardent creatures, the spring mating season is the best time to make the attempt. However, if more than two strangers encroach upon butterfrogs during mating season, the entire group will disperse.
A rare butterfrog will allow a druid or ranger to take it as an animal companion, or, even more rarely, by allowing a witch or wizard to take it as a familiar. This tame creature grows accustomed to the hustle and bustle of society while repressing its mating urges for a season or two. Compassionate characters will release a companion butterfrog into the wild during mating season with relative assurance that the creature will return to them after their week-long frenzy.
Due to the butterfrogs' faerie origins, many of the creatures make their homes near faerie realms. In primal forests and swamps, fey creatures enlist butterfrogs for protection; adventurers trespassing in these areas speak of pixie cavaliers and knights riding butterfrogs in a charge against the trespassers. Centuries-old butterfrogs or large concentrations of the creatures typically, but not always, indicate the presence of nearby portals to fey lands.
