Elvira’s House of Mystery 11 (1987)

The “Find Cain” contest comes to a head but Cain is having a difficult time recalling where he’s been. He mentions spending time with, “this swamp monster–” …along with a blue beetle and a house of weirdness.

This little mention/reference is up for debate.
Is this “swamp monster”, Swamp Thing or is it referencing another swamp dweller from any number of DC’s horror books?

I’ve not read this entire Elvira mini-series so I could be missing the boat altogether. I’d like to think the swamp monster in question is none other than Swamp Thing. After all, Swampy’s first appearance was in House of Secrets 92, hosted by Cain and Able.
