I entered the playroom to clean up tonight to find this:
More grisly evidence:
The main suspect unfortunately was asleep at the time of my discovery so I was unable to question him. However, my instincts suspect this is a case of “busy parents/bored child/cool new tools” syndrome. I returned all evidence to the knitting bag for later repairs, as it was too dreadful to attempt tonight.
Anyone know how much it would cost me to add a studio onto the house? One that locks?
