In "Naughty Nymphs", the nymphs magically transform Paige into a nymph.

In Greek mythology, nymphs are spirits of nature and they were an important part of Greek mythology and religion. They are minor female deities and the protectors of springs, mountains, and rivers. They were revered as the spirits of specific natural features like mountains, rivers, trees, and even groves were usually associated with a type of nymph. The name "nymph" comes from the Greek word that means "young woman", and so naturally these beings were considered to be female.

Dryads and hamadryads are two types of wood nymphs in Greek mythology. These female nature spirits were thought to inhabit trees and forests, and they were especially fond of oak trees. Dryads were often depicted in myth and art accompanied or being pursued by their male counterparts, the satyrs (satyrs were male creatures who inhabited woodlands and forests in Greek mythology). Each one is born with a certain tree over which she watches. A dryad either lives in a tree, in which case she is called a hamadryad. The lives of the dryads are connected with that of the trees; should the tree perish, then she dies with it. If this is caused by a mortal, the gods will punish him for that deed,

There are many stories of dryads in myth and legend, One famous dryad was Eurydice, the beautiful but ill-fated wife of Orpheus (Orpheus was a legendary singer and musician in Greek mythology), According to the tale, Eurydice was killed by a snake when she tried to escape from the unwelcome amorous advances of Aristaeus, The fact that a dryad such as Eurydice could die demonstrates the idea that these nymphs were not immortal, And indeed, the hamadryads were even more vulnerable, for it was believed that their lives depended on the health and well-being of the trees they inhabited, The myth of Erysichthon illustrates this point,

Erysichthon needed wood to build a hall, so one day he entered a grove of oak trees. Now, this particular grove was sacred to the goddess Demeter, (the goddess of grain and fertility) and was also a favorite location of those gentle nature spirits, the dryads. But these facts seemed lost on Erysichthon. He simply starting chopping down the largest, oldest tree standing. At first strike of his axe, the tree began to bleed. Undaunted, Erysichthon continued to cut through the bleeding bark. Then he heard a sound coming from the wounded tree. It was the voice of the hamadryad who lived in the oak. She begged Erysichthon to stop, telling the heartless man that not only was he killing her tree, he was also murdering her in the process. Erysichthon ignored her pleas. Eventually the helpless hamadryad died, along with her beloved oak tree. The goddess Demeter learned of this horrible crime from the other dryads who inhabited the grove. In the end, Erysichthon was punished for defiling Demeter's sacred grove and taking the life of a hamadryad.

Nereids were nymphs of the sea in Greek mythology. The ancient Greek poet Hesiod states that the Nereids were the daughters of Nereus (a sea god) and Doris (an Oceanid). In addition, the poet claims that there were fifty of these nymphs.

The Naiads were nymphs of bodies of fresh water and were one of the three main classes of water nymphs.The Naiads presided over rivers, streams, brooks, springs, fountains, lakes, ponds, wells, and marshes. They were divided into various subclasses: Crinaeae (fountains), Pegaeae (springs), Eleionomae (marshes), Potameides (rivers), and Limnades or Limnatides (lakes). Roman sources even assigned custody of the rivers of Hades (Hades is the lord of the dead and ruler of the nether world, which is referred to as the domain of Hades or, by transference, as Hades alone. He is the son of Cronus and Rhea.) to Naiads classified as Nymphae Infernae Paludis or the Avernales.

The Naiad was intimately connected to her body of water and her very existence seems to have depended on it. If a stream dried up, its Naiad expired. The waters over which Naiads presided were thought to be endowed with inspirational, medicinal, or prophetic powers. Thus the Naiads were frequently worshipped by the ancient Greeks in association with divinities of fertility and growth.

The genealogy of the Naiads varies according to geographic region and literary source. Naiads were either daughters of Zeus, daughters of various river gods, or simply part of the vast family of the Titan Oceanus. Like all the nymphs, the Naiads were in many ways female sex symbols of the ancient world and played the part of both the seduced and the seducer. Zeus in particular seems to have enjoyed the favors of countless Naiads and the other gods do not seem to have lagged far behind. The Naiads fell in love with and actively pursued mortals as well. Classical literature abounds with the stories of their love affairs with gods and men and with the tales of their resulting children.

Stories of the Naiads could take the form of cautionary tales with unhappy endings. The Naiad, Nomia, fell in love with a handsome shepherd named Daphnis and could not do enough for him. He repaid her love with unfaithfulness and she repaid his inconstancy by blinding him. The Naiads of a spring in Bithynia took a liking to Hylas (companion of Heracles) and lured him into their waters. The cautionary element is uncertain here. The fate of Hylas could have been either an abrupt death by drowning or everlasting sexual bliss.

Other stories of the Naiads were explanations of the origins of immortals and mortals. The sun god Helios mated with the Naiad Aegle (renowned as the most beautiful of the Naiads) to produce the Charites. Melite, a Naiad of the Aegaeus River in Corcyra, had a liaison with Heracles and became the mother of Hyllus. Naiads were the lovers of Endymion, Erichthonius, Magnes, Lelex, Oebalus, Otrynteus, Icarius, and Thyestes and were therefore co-founders of important families.

Greek towns and cities were called after the names of Naiads. Lilaea, in Phocis, was named for Lilaea, the Naiad of the Cephissus River.

There is a reference in Homer's Odyssey to a cave, rather than a body of water, that is sacred to the Naiads. It might be assumed, therefore, that this cave in Ithaca may have contained a spring or have been the source of a stream or brook.

In Greek mythology, the Oceanids were beautiful sea-nymphs. According to the Greek poet Hesiod, these nymphs were the daughters of the Titans Okeanos and Tethys. The word Oceanid is derived from the name Okeanos (which is also spelled Oceanus). Hesiod claims that there were three thousand of these sea-nymphs who inhabited the waters.

In Greek Mythology Oreads were nymphs of mountains. They belong to the retinue of Aphrodite (In Greek mythology, Aphrodite is the goddess of love, beauty and sexual rapture).

Leimoniads were nymphs of the meadow.

Meliae were nymphs of a particular kind of tree, which was the ash tree.

Limniads were nymphs of lakes, marshes and swamps.

Napaea were nymphs of valleys.
