Slime dripping off a Lovecraftian Worm

This is my very first post, I found out about this forum by watching one of Terrain Wench's Summer 2015 Update.

Here is my question, I'm building a gigantic Lovecraftian worm and I'm going to have it come out of water in a swamp, since it's just rising out of the water I would like for slime to look like it's about to drip off the worm. So what technique should I use for this please and thank you! Smile
