Nabasu has a brown and cream fur and mark of hair on his head, his face and his ears are pink, his head and his back are dark brown, his chest are light tan, his paw and feet are black, his eyes are brown, and his furry tail.
Likely his sister, Nabasu is amiable, playful, friendly. He loves excitement and enjoys playing in Hot Springs.
Nabasu is seen with his family, enjoying the hot springs. When Anga approaches them to ask a question, they are frightened of her presence, and scare her away with snowballs. As Kion uses his Roar of the Elders in an attempt to create a shortcut through the mountain, it causes an avalanche which Nabasu's family are caught in. After being saved by the Guard, Kion offers to find them a new home.
They stop off at some new hot springs, but are startled by Tafu's Scurry, who were only trying to say hello to their new neighbours. However, their commotion causes Nabasu and his family run.
They fall into a pit, and an attempt by Bunga to save them is futile. Anga is able to fly down and rescue them all together, where they finally learn to accept her. Anga scouts out a new hot spring, and Nabasu and his family leap in. Along with his sister Kimyo, the two persuade Anga to enter the springs with them, where the eagle joins in by lightly splashing the siblings.
