The Glowcroak is a small animal from the swamp regions of Vivatus.
Three centimetres long, the glowcroak is a tiny, large-bellied organism with a wide mouth and four legs ending in little fins to allow it to swim through the swamp. It consumes the scum on the swamp surface, such as Glashrooms.
They are bioluminescent, males emitting a yellow light and females emitting red. This is believed to be for communications and sexual display. Males attempt to mate whenever they locate a female.
