There are blender videos that show how to get a slime material. Then you can bake the result to texture. If the slime is meant to be see-through, you can assign a simglass shader in the warehouse to enable transparency.
PLEASE FOLLOW THE RULES OF CREATOR HELP:
describe your problem and provide a picture of it (if possible);
provide download link(s) to .package and .blend files.
If you have a Gmail acc, you can host all of the above on Google Drive
