I looked down and saw all this slimy stuff on the hall floor, in little puddles.

They was all covered with a grey, slimy stuff that looked like the scum on top of bad preserves.

"Me eating in the other room is going to be part of the pregnancy, too, you keep slurping that slimy stuff down."

Suddenly I start puking into the road, but nothing comes up except this slimy stuff.

"But what's that black slimy stuff at the bottom?"

It looks like the slimy green stuff Harry has been complaining about.

The slimy stuff took a tenacious grip on whatever it found.

Some were empty but others held several tons of slightly slimy whitish stuff.

It may be the most dangerous green slimy stuff on Earth!
