Stoutland is a canine Pokémon with a talent for rescuing people lost at sea or in the mountains. On its face, it has cream-colored fur that forms voluminous, white-tipped plumes and a three-pointed crest. The plumes are so long that they run the length of its body and bunch close to it. It has tufty, pointed ears with dark blue insides, and black nose surrounded by short black whiskers, and small eyes that are nearly hidden behind its facial fur. Its body is covered with shaggy fur that is dark blue along the back and grayish blue toward the legs. This fur is thick enough to protect itself and others against freezing temperatures. Its face and paws are light brown, and each paw has three toes with white claws. Blue paw pads can also be seen on each paw in Pokédex 3D Pro.
An old Stoutland first appeared in That's Why Litten is a Scamp! living in a abandoned house with a wild Litten. It reappeared again in SM016, this time living under a canal bridge. It reappeared in SM021 where it's help had gotten bad and was taken to Nurse Joy for treatment. After being discharged, Stoutland disappeared leaving Litten upset.
