A running routine was that any time anyone said "I don't know," he got green slime dumped on his head.

What the novel finally boils down to is mostly green slime.

A touch of current and he wouldn't care if Harkabeeparolyn turned to green slime before his eyes.

"Bones has already got the green slime mixed for me."

"I know you've already got the green slime growing," Jim said.

Then he gets wet all over like with green slime.

If green slime could be transmuted to fire, it would have that look.

"Another body of water fills with green slime and poison?"

Looking down, he could see fallen stones, green with water slime.

And he was covered all over in thick green slime.
