Ick. One of my cousins used to work at a kids' playroom and she had to clean up the worst crap that rugrats left behind in those ballpits (so those things are ballpit balls or ballpool balls, among other names.) However, her favourite horror story involves a very irresponsible father who let his
very non-toilet-trained two-and-a-half-year-old son romp around in the ballpit... The little tyke was having so much fun in the pit that it didn't occur to him that he was supposed to get out of the pit to go potty.
My cousin eventually quit her job, but not until after she had to help dispose of thousands of coloured balls.
Bazinga!
