Ecology

Giant frogs inhabit slow-moving freshwater swamps, mangrove deltas, and forest bogs where rotting log mats float with insect larvae. They prey on rodents, birds, fish, and any humanoid small enough to swallow. Females lay clutches of several thousand eggs in surface foam, of which only a handful survive past tadpole stage. They require warm water and become torpid in cold climates, hibernating in mud through winter months.

Behaviour

Giant frogs are patient ambush predators, sitting motionless for hours with only their eyes above water. They strike when a vibration crosses their lateral line, lunging once and retreating with prey. They are solitary outside breeding season, when males call in deafening choruses that can deafen smaller creatures. They are unaligned and unintelligent, driven entirely by hunger, territory, and reproductive instinct.

Origin

Most giant frogs are simply oversized natural amphibians, products of fey magic seeping into amphibian eggs in fey-touched swamps. A few subspecies are deliberate creations of Druidic circles seeking guard-beasts for sacred bogs. Older legends speak of the first giant frog as a punished trickster god transformed for stealing a celestial pond, and any frog of unusual size is said to share a drop of his shamed blood.
