Note: If you post an idea in this thread it means you allow us to put part of it or all of it in the game Unclaimed World. If you've been inspired by an existing concept made up by someone else or seen in another film/game/book, please tell us and if possible include a link to the source.
Some of our ideas for your inspiration (as always, our plans may change depending on what's fun/realizable)
The orange grass covering many parts of the planet is called firegrass and competes with the blue/green muckroot which is a sort of moss. Muckroot can transport water over large distances through its fleshy web of veins, which means that it can spread into arid areas. Wherever muckroot is, there's a host of fungus-like or spungy growths called greentubs and goblin sprouts. It is preyed on by a parasitic circular plant called demon ring. Animals appearing here include the territorial patrician (seen fighting with a competitor in teaser video#2). This exoskeletal animal kills by stabbing with powerful poisonous limbs. It is slow moving and lords jealously over its territory where it has its prey - slugs and fish that swim inside the muckroot water canals. It stabs them through the canal wall, dissolving their insides and sucking up their juices.

The sanctuary tree (top left) can keep muckroot at bay, often creating islands of firegrass biomes within "seas" of muckroot. The firegrass biome is much more agreeable to humans, and is characterized by a tree called the spoak (=spiral oak) and the other yellowleaved plants, wingweed and shadeleaf. Here you'll find the turnip, a lumbering, plated grazer with sensory tentacles on the top. It was given that name because it leaves an egg buried in the ground, which somewhat resembles a turnip once it emerges.
Other creatures you see in the video are the pack-hunting "twinklers" (named for their communication organs that glow and flicker in the dark) often preying on flocks of "thunder chicken", a tasty herbivore which picks food from the ground with two grabbing tentacles while its third, sensory tentacle keeps watch.
There is also the slow-moving bush dragon, which defends itself and its calves by confusing predators with its extendable, reflective wings, and if necessary, by excreting a powerful spray of chemicals.
