There are organic rocks, like Limestone, and clastic (composed of fragments), like Sandstone. Within these groups there are others, like coal is organic and siltstone is clastic, but even within limestone and sandstone, there are further categories. There's oolitic limestone, chalk and 'shelly' limestones; and arkose, desert sandstone, orthoquartzite (generic sandstone), and others. Conglomerate is an interesting one, if you are after a rock that is not 'normal'.
the limestone gets crush into tiny particle and joins the othe marterials

Coquina is a sedimentary rock made up of shells, shell fragments, and skeletons of small marine creatures.
Rain water can dissolve rocks like limestone.
It's always in a sedimentary rock, but mostly they will be found in a limestone. Some limestones, like the 'shelly' limestone, will be more likely to contain shells than others, like the oolitic limestone (which is not made out of shells). Again, bones will tend to be found in sedimentary rocks, but the actual bones will tend to have dissolved and been replaced by rock minerals which precipitated out of solution to fill the 'mould' left by the bone (unless they were deposited recently, in which case you're more likely to find them in unconsolidated sediment like sand/mud).
hunter shelly is hunter shelly
The answer is a matter of opinion. It depends on what you like about each moshling. Some might like Shelly better because Shelly is easier to attract. Some might like Liberty better because you have to be a paid Moshi Member to get her. Or they might like one or the other better because of the way they look or because of the things they like.

Limestone is formed from particles derived from organic processes, usually in a marine environment. Sandstone particles are derived from the weathering and erosion of silicate bearing rocks, normally.
Limestone and places like limestone caverns.
