That is priceless! I was wondering the same thing, what is he doing with the crushed bugs?
When my DD was that age she used to take some of the lunch she didn't finish into her room and put it in her toy chest, without my knowing it. When I found it I asked what it was doing in there and her response was, "For later." 28 years later she still loves left overs but she doesn't hide them in her bedroom. (She is one of those people that only eats when she is hungry so doesn't over-eat.)
