What this on my live rock?

getting a good freebie is great before and after knowing its in your tank. getting a bad freebie makes for a bad day after its in your tank and didnt know you put it in there. and nothing good happens in this hobby fast.

Well, I was looking at the rock again and now I found something that looks like a sea cucumber but it is red and a couple of inches long. I ran to get the camera and when I got backs it was almost in a hole. Do you have any idea if it is bad? I will try to get a picture if it comes out again.
