Little things stuck on tank and decorations.

I just bought a used 20 gal tank and on the bottom and on a couple of decorations there are these little fuzzy things. They are about 5mm long. Can anyone tell me what they are and if I need to be worried.

It's hard to tell. Are you sure that isn't sand? It could be sand stuck to a sponge.....

maybe a snail egg pouch?
