This is the last of 4 posts i'll be uploading. These are updates to the original post I made with updated information and new art. I thank user Kjqaz for the additional information!
The Ghost slime only comes out at night, However they are crazy transparent and hard to see.
although they are hard to see, if put into a corral with a solar shield, you will be able to see their adorable faces so much easier. Just be careful, they are escape artists!
