Yo everybody, here's the finished image on my farting creatures.
Here's the description I gave along with the piece:
[To be read in the voice of David Attenborough]:
It's mating season in wetlands of Bumeria. Animals gather round the ponds and bear witness to one of the most unique mating rituals... in the world. Loud sounds echo across the ponds of the Bumerian landscape, as these creatures court one another. The Organ-backed Pondlok... The males will sit on a lily pad, using their organ like flatulating tubes to create music... Females will skitter across the surface of the water like hovercrafts seeking the male with loudest, most melodic and (of course) most pungent song... once they have located the desired male, they will approach the male and begin to play the same song in unison. If the song lasts for more than a minure, this means it is time to mate. The male and female dive underwater where the male shoots his spore-like sperm toward the female's cloaca. The female then nurses the eggs in an underwater nest, until it is time to hatch... The male, tired from expelling most of it's gas from the mating process, dies a short while later.
