W, E, R, P, 9

I'm not sure if this is some kind of secret toddler language or if I'm supposed to start searching for clues like in The Davinci Code but I just came in the bedroom to find a few letters (and one number) ripped off of our laptop keyboard!!! Mr E came in and handed me a W... uh oh. Luckily I found them all and they snap right back on. lol I'm thinking I should break out Scrabble?
