Being one of the biggest Hidden Critters ever recorded, it comes as a big surprise to note how far off into our excursions we managed to discover this behemoth. The Prismatic Frillback can be best described as a flying whale of titanic proportions. True to their namesake, the frills on their backs look like feathers, and they allow these large creatures change colors and camouflage themselves high up in the skies. These frills also contain symbiotic photosynthesizing bacteria that give them sustenance. 

They live their entire lives lazily drifting among slow moving clouds. These highly intelligent critters form deep relationships with each other, and they’ve developed a complex language composed of deep guttural growls that can be easily confused with distant thunder.

Frillbacks are inquisitive creatures who can form bonds with other species. They’ve been recorded playing with Lofty Cloudweavers; the smaller dragons weave their wool around the Frillbacks and decorate them while the Frillbacks roll in midair. While they usually sleep while floating, Frillbacks sometimes land on sky islands to rest from long journeys.
