What in the world?!

[Saltyteacher]

I'm about 3 weeks into the hobby and I found something gorgeous, but I have no idea what it is. For about 36 hours it's been on the front side of this rock. My LFS thinks it's some type of sea slug. I finally noticed a little movement (maybe .25 inches) this evening. At first I thought it was a coral but now I have no idea. Can anyone help me?

One more pic so you can see movement.

Me too! The blue is so vibrant!! It is beautiful. My daughter calls it Elsa because its back looks like snowflakes.

Looks like a blue lettuce sea slug to me. Google it and compare other images to confirm. If true, awesome hitchhiker.
