I see. This is a weird situation, then, and I apologize if I was abrasive.

Searching online ("Deep down here by the dark water lived old Gollum. I don't know") there are many hits for the line without "small and slimy creature." I assume it to be part of some legitimate edition, and I find it hard to believe this clarification would have been removed between editions, so with some confidence I conclude the original version did not have "small and slimy creature." Still, I understand your POV and appreciate your patience explaining it.
