I am constantly finding some little item (a snail's shell in this picture) in a particular candle we have. Being I have a son with a certain fondness towards small random things, I was not at a loss for how they appear there, but I finally learned why they are put there.
Jake: "Mom, where'd my playmobil flashlight go?"
Me: "I put it with the playmobil; why do you put things there in the first place?"
Jake: "Safekeeping....Max hasn't thought to look there yet."
