::: This relative motion represents kinetic energy that belongs to individual billard balls within the blob, not to the blob as a whole, so because of conservation of energy, the energy we can ascribe to the blob as a whole is going to decrease, and so is the average velocity of the blob.

::: I '''think''' that what the Second Law is saying is that the way in which the blob hits the wall is essentially random, and that with each impact, statistically, more and more energy is going to end up in the form of billard balls oscillating with respect to each other within the blob, and less and less organized motion of the entire blob as a whole.

::: So that whereas the motion of the single billard ball "never stops," after a while the motion '''of the blob''' has stopped, and instead you just have a stationary blob with the billard balls within it oscillating on their springs.
