Not sure when or who but clearly, someone in the house stepped on the xylophone. My money is on Joseph. He's already broken more toys than Will and Will's three years older. I wouldn't say Joseph is destructive but he does have a knack for throwing things. He even broke a Thomas the Train piece with a well-aimed rocket throw and those things are indestructible! We're working on how to take care of our toys.
In the meantime, what to do with these groovy plates?! Chris suggested making another xylophone. My first thought was a necklace. A quick search on google brings up the idea of a wind chime.
