snail? and fuzzy round things?

[clownfish cj]

I have several white fuzzy round things growing on my rock and I also found this little creature that looks like a snail but it only has a small piece of shell on top and it moves faster then a snail.

cant really tell by the pics but most likely a stomatella snail and some sort of sponge probably a pineapple sponge

I just looked up stomatella snails and that is it! It must have hitch hiked on the 12 pounds of cured live rock I added to my tank 5 days ago, cool.
