This spell turns the caster into a fish, and grants the ability to converse with other aquatic creatures. The difficulties of breathing underwater have meant that Nature's Tongue has never been a practicable method of communicating with fish, making this spell the only real option if you wish to gain a deeper understanding of life beneath the water's surface. Some claim that fish have a clearer view of the world than those who dwell on land - but clarity should not be confused with wisdom.
Werefish is a spell that allows the caster to become a fish and discover the joys of life aquatic. Oliver obtains this spell in the Fairyground from the Fairy Godmother. It is, however, unusable.
