Waltur Paints Himself Into a Corner

Waltur and his friends Matilda and Darwin are back in this collection of three stories that help beginning readers understand funny everyday sayings--like trying not to paint yourself into a corner (easier said than done!), putting the cart before the horse (how backwards can you get?), and letting sleeping dogs lie (not much good can come from waking up a cranky dog!).
What kind of trouble will Waltur get himself into this time? How much the wiser will he be for it?
