Canine companions Big Dog and Little Dog are always getting into sticky situations. Their second adventure is about a particularly muddy situation! But friends who endure baths together are friends 'til the end--or, at least until their next muddy walk. With simple text, graphic illustrations, and tongue-in-cheek humor, Captain Underpants creator Dav Pilkey taps into the joys of childhood friendships through his tales of two lovable dog pals. This Green Light Reader will help children build basic reading skills while also tickling their funny bones. Look for skill-building exercises in the bonus activity section at the back of the book.
