Skulk algae!

Imagine a mob dies near a skulk catalist what happens? Well skulk grows there but what if a mob dies in water now what happens? I feel players are going to run into this problem and its going to be confusing for them so i feel there should be skulk algae its kind of like normal skulk blocks but its texture is a bit bluer and it has a special feature to it. much like the other skulk blocks it reacts to sound if you make any sound it will make you sink into it but it will act as a solid block if you are quite and crouching however this does not aply to the warden it wouldent sink like the player would
