Silly Goose
Silly Geese are a species of mutated Canadian Geese native to the land of Eden. They are distinguished from their mundane ancestors by their distinctive honk. This amused and amusing call is known to induce laughter in nearly all who hear it—a contagious noise which has been known split sides and bust guts the world over.
That said, for those who are immune to the contagious chortling of the silly goose, the animal can be a fearsome adversary. Silly Geese have been known to attack any and all who do not laugh along with them, which is why they have become a favorite pet and sidekick of street performers and comedians the world over. If an Edenian comes across a busker telling jokes with a silly goose at his side, that Edenian best be prepared to laugh—or ready to run!
All geese are a--holes. This article is only further proof of that undeniable fact.
For your consideration, my submissions for the WorldAnvil Worldbuilding Awards 2024. (I've also included some of my favorites other worldbuilders.)
Wait until you see the picture. I finally found a goose model I could download for free and I've got it rendering now. He's standing beside a court jester who's looking at the camera and basically daring the viewer not to laugh.
