Breath in, Breath out.
Oxy slimes cannot make largos. They float around in a corral and produce plorts every 2 hours (in-game). Oxy plorts also float around, making them a bit harder to get, they start off at 50 n and fluctuate between 25-95. They spawn naturally in the Permafrost Mountains.
None, didn't think of one.
Oxy slimes seem to trap pure oxygen in a hardened plort-shell, breaking this shell releases the pure oxygen
They can bump too much into the airnet and escape. Otherwise, no. They cannot form tarrs.
Oxy slime plorts are valued for their use in oxygen tanks and air conditioners, as they decompose into oxygen over time.
Like a puff of gas.
