Digger (voiced by Shelley Longworth) is a Labrador Retriever puppy. He is the youngest of the four friends and always eager to prove himself. He is very cute, naive and willing to please. Digger has boundless energy and will always be the first to volunteer for any new adventure. He isn't very bright and so doesn't come up with as many ideas as the others and sometimes takes a while to catch on to what’s happening. But Digger is always eager to please and is never happier when playing with his friends. His catchphrase is "I can do that! I can do that!"
