Ooze, The (Ghosts of Fear Street #8) by R.L. Stine - Vintage Paperback

Al's stink bomb doesn't explode... And it doesn't smell. It just sits there.

Some chemistry set, Al thinks. Big deal.

And then it starts to ooze. It oozes all over the cat. It oozes all over Al's best friend.

Everything the ooze touches...changes. Forever.

And now the ooze is coming right at Al!
