I did something similar when I was a toddler
...left alone in my room while my dad watched football on the other side of the house, I painted the walls and a bit of carpet.

I was lucky with my two.....they never felt the need to play with their poo. However, I must have lost track of time and how old they are because I realized it was time to potty train when I caught the older one changing her younger sister's diaper.....then her own diaper. I started potty training that day.
