I second this suggestion! My boys keep tossing them under the oven or under the door of a VERY full closet, and I'm too lazy to dig them out often. So I've bought like 4 or 5 packages of them, and then when they've all disappeared I will go spelunking under my oven and in the closets to gather them all up again.They come ten to a package but tend to get shoved under everything like mousies do. So you will want several packages.
