coralline algae comes in many colors.

 

[Adio800]

So is there a chance it is.. I know it comes in alot of colors

 

[Skaterbarney]

I know it's comes in different colors but it's usually bright purple, to me that looks some what like a sponge.

 

[Adio800]

It's for sure a rock with something on it here's pic of other rock
