Bubbles

The Bubbles are stationary creatures shown in the trailer. They do not appear in the final game, and have no official name as of yet. The Bubbles themselves are not alive, but are rather created by some sort of creature that lives inside of the shortcut the Bubbles rest on. The creatures are said to eat Batflies. It is presumed that slugcat is not affected by the Bubbles, as they can be seen popping when pounced on and do not seem big enough to catch slugcat.
