It was fun to read about a younger Emmet. I also like how you pointed out just how much effort is really needed to use a rattle. The simplest motion will set about the sounds necessary to make any tot feel like a talented musician.

You also did a great job in describing all the steps necessary for our Eevee friend to drop the deuce. Compared to the rattle, making a number two is certainly far harder to do. This easily explains why Emmet is forced to focus on his pamper packing instead of the rattle he was thoroughly enjoying.

The full fill of making tinkles in his crinkles also shows just how much attention, energy, and exertion a tot like Emmet has to do in order to relinquish those unwanted substances from his healthy, young body. However, unlike the poo he had to do, a piddle still allows the little fellow to play with his rattle due to #1 being less effort than that forceful push to get out the mush.
