With the upcoming DLC on its way and a ravenous modding community avaliable, figured I'd throw a critter suggestion at you all.
So far we've got a quite a few useful industrial critters in the Hatch, Slickster, Drecko, pokeshell and pips for those massive natural farms. A missing niche however, is a critter to run those farms. Many seem to automate their farms by increasing their overall volume and allowing the plants to simply auto harvest when left alone for too long. An easy, elegant solution to maximize duplicant productivity. But space is precious, and we then have the additional time and resource investments required of the larger farm space.
In comes the Kombodillo.
Appearance wise they're an armadillo with a cylindrical head orientated horizontally, traverse similar to a drecko however are unable to jump block gaps. They have a small combine harvester like tool in this cylinder.
In my head this would be a lategame critter with a very narrow range of atmospheric requirements: an extremely narrow temp range (maximum variation of 30 degrees), an atmospheric range of 500, require either light/darkness depending on variant (base variant requires dark) and consume a gas/liquid with germs in it for calories when tamed (germ type specific to the critter variant) [food requirement pending, wanted to make it hard]. In order to increase versatility, variants can be bred with different requirements so they can be utilized effecitively for any plant farm.
This demand on the player is rewarded with their function, the Kombodillo behaves like a combine harvester when awake. The Kombodillo will traverse the world like a drecko but unable to jump, seeking out and harvesting any plants they pass over that are harvestable and dropping the seeds/food on the ground, jealous of their growth. When tamed/fed, the Kombodillo traverses ate a greater rate, allowing fewer Kombodillos to handle a larger farm. This can be combined with auto loaders/receptacles/sweepers to compltely automate the crop farming process.
This will allow for auto harvesting of natural/planted crops without the need for duplicant intervention but of course with a tedious and potentially difficult environmental/breeding requirement. Due to their traversal abilities, they can harvest ground/ceiling bound plants as well as water bound plants.
