What is this???

ok...well after my bubble coral fell today I had to redo some rock work to get it to stay in place. While moving some rocks in the sand, I found thing green thing that looks like a chili peper! after pushing it to the side I noticed it was moving...after a few seconds it was streaching all out wiggling along the sand! Freaky I must say...since I had no idea what it was I threw it in my refigium where it burried itself rigt under the sand within minutes. Any idea what this thing is or where it came from?? THanks guys!

Could it be a cucumber of some sort? How big is it?

or a sea squirt?

I could tell you what it looks like in the second pic but i'm sure you can figure it out....i'd say a sea cucumber but i've rarely seen them not attached to LR
is it a hard shell like thingy? or all soft? how fast does it move ..need more info

it was about 1" when I found it but it streached out over 3". I have an Atlantic Cucumber and it looks nothing like it. It was soft...its you can see its internal organs as it moved. I am pretty sure its not a sea squirt, all the ones Ive ever seen ahve been attacked to a rock...it moved a little faster then my cucumber, but it went right underneth the sand. I am really clueless as to what this thing is!! should I take it out of my refugium?
