Tommy: "Mom! C'mere quick!"
Me (Oh God no, what now?) : "Why, honey?"
Tommy: "Canny! Mess! Canny mess!"
Me (getting up and following him into his bedroom): "Where? Show me."
Tommy (pointing to a mess of bright red handprints all over his mattress) "There."
Me: "Who did this?"
Tommy: "Danny the baby."
Tommy: "Waycho's canny. Waycho's mommy canny."
And now it all makes sense. Danny found a piece of Twizzler (Rachael candy) which Rachael's Mommy very kindly gave to Tommy and Rachael, and chewed it into a red pulpy mess. Also, he seems to have spit the mess out onto the floor, and it dried into the carpet. I think I'll make Tom clean that part up.
