You'd think after four kids I would know what it means when there is absolute silence with a toddler in the house and it's not nap time.
Today this is what it meant. Seth found a box I didn't even know I had, in a bag downstairs with all my colored pencils in it. There was one purple marker. 

Pretty sure it made it in his mouth too as his tongue is slightly purple. Also pretty sure he tried coloring his pants as he kept looking at them like he was trying to find his art work but they are black so it's all good :)
