Stuffs growing on shells

[Vt328aa]

Can someone help me identify the red thing growing on top of the snail shell? The shell came as part of clean up crew that I bought from a seller in Florida. Thanks.

Which one is the snail? The spike hair or the little round bobs?

The snail is in the foreground, center of the picture, with the spike hair.
