His name may be a reference to the famous Australian song "Waltzing Matilda". His name may also be derived from Walt Disney who first drew the kangaroo mascot for the University of Missouri, Kansas City: Kasey the Kangaroo. His phrase may be based on the pouch or pocket female kangaroos possess.
Walt is a light grayish-blue kangaroo. He has a grey muzzle and belly, black nose, closed eyes, and thick black eyebrows. He has bandages on both forearms and a white scar under his left eye. His paws and feet are gray, and the insides of his ears are yellow. In New Leaf, he initially wears a Jinbei Top. In New Horizons, he wears a Casual Kimono.
Below is a brief description of the cranky personality. For more information, click here.
Cranky villagers will usually appear in a grouchy or agitated mood and are more difficult to befriend than most other villager types. When talking to the player, cranky villagers tend to become angry if the player disagrees with them or refuses to do a favor. Like all cranky villagers, Walt will be invested in his hobby and will often challenge the player to various competitions. He will easily get along with jock, snooty and other cranky villagers, and occasionally lazy and normal villagers as well. However, he will find it hard to socialize with peppy villagers, as they will seem overstimulated or immature. Walt will also enjoy spreading rumors about other villagers.
In New Leaf, Walt's house resembles a Japanese garden (日本庭園, nihon teien), with a deer scare, salmon, bench, bonsai, raccoon figurine, clothesline pole, lamp, tall lantern, and an outdoor bath. He uses the mossy carpet as flooring and the garden wall as wallpaper.
In New Horizons, Walt's house maintains a garden theme, as he has a deer scare, raccoon figurine, simple well, bamboo bench, pond stone, bonsai shelf, and a bamboo speaker that plays K.K. Lament. He uses the bamboo-grove wall as wallpaper, and the mossy-garden flooring as flooring.
