What does "thick" mean in this context? It seems it means more than thickness!

"Thick" is referring to the consistency of the mud. If a substance or liquid is described as being thick, it means that it is dense, heavy, and does not flow freely. Ex: I ordered a milkshake. It was very thick and delicious. Ex: This soup is too thick. You should add more water to it.
