slug/snail id help

[metone]

i found this thing "growing" on my live rock about a month ago. has not moved. came right up off the rock. seems to have green patches coloring up on it...maybe a juv. crispata? also upon closer inspection seems to have "built" or 'grown" a tunnel of the same color white that it slips in and out of. hard to explain without legnthy post.

hard to explain without legnthy post. Get posting! :D I see a shape that reminds me of a limpet, but that is just a wild guess. Hope someone else can do better than me. :(
